What about a show that had a down season somewhere in the middle of its run?If you're putting together a list of your top 5 shows of all time I think it should go without saying that the show has to be brilliant from start to finish of it's run. there's no way you should be including a show that fizzled out at the end.
I'd say it's relative. If a show was your very, very favorite, it might be able to withstand a bad series finale. It might be the tie-breaker that works against another show, though. I thought the finale of The Sopranos was a cop-out, for example, but the show was so strong overall it stays in my top 5.
Breaking Bad, M*A*S*HInteresting question: What shows do you think had the best finishes?
For me, off the top of my head it's Breaking Bad and The Shield. Those two had perfect endings...especially the Shield with the ironic ending of the Vic Mackey's character.
