A Touch of Frost. Lasted 18 years but with David Jason's age it was inevitable. As it is compulsory to retire from the Police Force at age 60 and Jason was 70 by the time the show ended it really wouldn't have been realistic, even though it lost none of its quality and only seemed to get better as time went on.
Definitely the best cartoon with Spidey so far, it was so good, they were really nuts to cancel it and replace it with this crappy Ultimate Spider-man. :[
Gilmore Girls Friends 8 Simple Rules ER NHL games being broadcast on channel 5 And am annoyed at channel 4 for selling Glee to sky... now I have to watch it online so the quality isn't as good
