"Supernatural" Review: Fifteen Seasons, and the Five That Were the Plan

Two brothers, a 1967 Impala, and a road that runs for 327 episodes. Supernatural is the show I have watched more times than any other, and it also has a very clear finish line that arrives ten seasons before the credits do. Here is what it does right, and where it stops.

Some shows you watch. This one got its hooks in me for more than a decade and never really let go. I finished all fifteen seasons from the start, then started again with the pilot. That is not a recommendation so much as a confession. Today is my birthday. So, who gives a shit, right?

Two Brothers and a Car

Sam and Dean Winchester hunt things. Ghosts at the small end, demons and angels and worse at the large end, and a great deal of regional American folklore in between. They have no home, no fixed address, and no visible income beyond credit card fraud. What they have is a 1967 Chevrolet Impala and the interstate.

The road is the whole thesis, and it is doing more work than it first appears. The show is built on the idea that you keep driving because stopping is not an option, and that the road eventually goes somewhere even when you cannot see the end of it from where you are sitting. That is a useful thing to be told when you are having a rough year. Sam and Dean take the longest possible version of that road, hit every obstacle it has, and still arrive.

The show treats the car as a character rather than a prop, and it makes that explicit. In the fifth-season finale, the narration stops the apocalypse dead to tell you where the Impala came from: a plant in Janesville, Wisconsin, in April 1967, and a chain of owners ending with John Winchester buying it on impulse. Fifteen seasons in, that car has more screen time than most of the cast.

The Casting Is the Whole Show

Jared Padalecki plays Sam, and Jensen Ackles plays Dean, and whatever the two of them have between them cannot be written into a script. It has to already be there.

The contrast is clean. Sam is the careful one, the one who reads the lore and thinks three moves ahead and wants a life outside the family business. Dean is instinct, appetite, and bravado, a man who solves problems by driving at them faster, and who has strong opinions about pie. Put them in a car for fifteen years, and the friction generates everything.

Dean is my favourite character in anything I have watched, and it took me a long time to work out why, because on paper he is the simpler of the two. The reason is that almost nothing he does is actually for himself. He raised his brother, took his father's orders, went to hell in Sam's place, and built an entire personality out of classic rock, cheap food, and deflection so nobody would look too closely at the rest. Jensen Ackles plays all of that at once. The jokes land, and you can still see what is underneath them, and when the show finally does look closely, in the seasons after hell and again after Purgatory, Ackles has somewhere to go because he has been laying the groundwork the whole time. He is very funny, and he is the saddest person in the show.

What makes it work is that neither is written as the correct one. Sam's caution gets people killed. Dean's recklessness saves them. Then it inverts. The show keeps finding new ways to put them on opposite sides of the same problem, and it never fully resolves because their argument drives it.

The supporting bench matters too. Castiel (Misha Collins) arrives in season four and never leaves. Bobby Singer (Jim Beaver) is the closest thing either brother has to a functioning father. Crowley (Mark Sheppard) is one of the great television villains precisely because he keeps refusing to stay a villain.

Monster of the Week, and Why It Works

Most episodes hand you something new. New town, new legend, new thing that should not exist. That structure is old-fashioned, and it is exactly why the show is so easy to keep watching: every episode is a complete meal, and the season arc builds underneath without demanding you sit through it in order.

It also gives the writers room to be strange. Over fifteen years, this show did a full body-swap comedy, an episode set entirely inside the car, a stretch where the brothers get trapped in television genres, and one where they wake up in our world playing actors named Jared and Jensen. Very few dramas can survive that kind of tonal swing. This one runs on it.

The cost of that structure is the filler. Some episodes exist because twenty-two of them had to be delivered that year, and you can feel it. There are fewer than the reputation suggests, and skipping them costs you nothing.

How It Got Made

Eric Kripke spent close to a decade pitching this show before anyone bought it. When The WB finally aired the pilot on 13 September 2005, roughly 5.7 million people watched, and the strength of the first four episodes got it a full season.

His original plan was three seasons. He stretched it to five, and the fifth was built to be the last: the apocalypse arc closed, the mythology finished, everything paid off. Then the network wanted more, and Kripke did not.

His reason is worth knowing because it is unusually candid. Twenty-two episodes a year had ground him down, and by season five he felt his own work getting sloppier for the first time. Rather than keep going on empty, he handed over to Sera Gamble and stepped back. Gamble ran seasons six and seven, Jeremy Carver took eight through eleven, and Andrew Dabb and Robert Singer brought it home. Singer, to his credit, was there for all fifteen years.

The show ran until 19 November 2020 and finished with 327 episodes, making it the longest-running American live-action fantasy series on television.

The Ending That Already Happened

Here is the part that a certain kind of fan will argue about forever, and I am that kind of fan.

"Swan Song," the twenty-second episode of season five, is a finale in the full sense. Every thread the show had been pulling since the pilot gets tied off. The story ends where it started, in Lawrence, Kansas. The narrator closes his book, says something to the effect that nothing ever truly ends, and disappears.

And then the last shot. A street lamp outside a suburban house flickers, and the camera pulls back from what should have been a peaceful closing image to let you sit with it.

That is a perfect final frame. It says the Winchesters are finished, and the world's evil is not; that the road goes on whether or not anyone is driving it. Ten more seasons followed, and some of them are excellent, but nothing after that point was ever built to be an ending, because the ending had already been written and aired in May 2010.

Seasons one through five are the show. Everything after is the encore.

Where to Start

If fifteen seasons sounds like a commitment you cannot make, don't make it. Watch the first five. That is a complete story with a beginning, a middle, and a close, and it is Kripke's actual vision rather than an extension of it.

If you get to the end of that and want more, it is waiting for you, and there are individual episodes in the back ten seasons as good as anything in the front five. If you don't want more, you haven't left anything unfinished. That is a rare thing to say about a show this long.

The Verdict

Saving people, hunting things, the family business. Fifteen years of it, and I would sit through all of it again tomorrow.

It is the best thing I have watched, and I say that knowing exactly where its best episode is and that it aired a decade before the finale. Both of those can be true. Start at the pilot and drive until you decide to stop.
