TV shows with were great till the end

[fatandwheezing]

With all the strange angry folk petitioning HBO about GoT, I got thinking about long running shows that were as good at they end as they were at the start.

I can't really think of many:
Heros was probably the biggest drop in quality
Lost probably the most widely derided to the point where anything involving Damon Lindelof puts me right off
Walking dead has been up and down in quality a lot over the seasons - although I've not watched the last season
Battlstar Galactica kept the quality up but the ending divided opinion
Sopranos ending the same

Other than the Wire and Breaking Bad, any others?

Killing Eve was OK, until they got to the end & set it up for KE2

I didn't mind that really, but I already knew there was a second series in the offing. I guess I mean long running series rather than a single season.
