Question of the Day - Which TV show/s should have ended much earlier than they did? (POLL)

Welcome to another Question of the Day. Today's question comes from @dupinka who asks.

"Which TV show/s should have ended much earlier than they did, or are/were being unnecessarily prolonged?!

Great question.

I'm going to be answering this for shows that are still on the air but feel free in the comments to use shows that have already ended that you feel went on too long.

For me it has to be One Tree Hill, currently just finishing it's 8th season. I think it should have ended after Season 7.

So what about you? Sound off in the comments which show(s) you think have gone on too long or went on too long and why, let us know also when they should have ended.

Vote in the poll below for current shows which are 5 or more seasons into their running life that you think should have ended already. You can vote for up to 3 Shows.

And please keep submitting your Questions of the Day Below using the form.
