My two cents on Futurama...
I think that the movies were the beginning of the end, and I wish they'd never been made. Bender's Big Score was enjoyable in a "OH GAAAWD IT'S NEW FUTURAMAAAAA" sort of enthused way, but it didn't bear rewatching and the subsequent movies were laugh-free for me. I had very muted expectations of the new Comedy Central season and it kinda lived up to them. I laughed at a few jokes, but it was just so weak, so limp and depressing, compared with the original run.
I don't know how much of that is "nostalgia", how much of it is legitimate. I got loved those first four (or five, depending where you look) seasons so much that maybe nothing was going to seem impressive, but I didn't even find the new Futurama to be good, let alone anywhere near the quality of the first run. It was rather like the Simpsons decline, except somehow more devastating in just how instant it was.
New seasons were really uneven but I have to say there were couple of really good episodes in there. Most of them were bad tho. The Late Philip J. Fry still managed to become one of my all time favorites.
