TV series that went on (or a going on) too long

[Frimley111R]

I love Big Bang Theory but the last series has seemed a bit 'Meh'. Its done all the geek jokes and now its getting a bit serious (relatively). I can't help thinking it's had its time.

Also, Suits was superb but it finished and that should be that but they are trying to resurrect it even though there's really no sensible way back.
