Ted [Celluloid Hero]
If you like Family Guy, odds are you'll like Ted. If you're not a fan of that type of humor, there's really no point for you to give Ted a chance. Seth MacFarlane has built his style over the years, and this is pretty much what we all expected.
Ted is a stuffed teddy bear who comes to life after his owner, John, wishes it. The premise is simple enough to just say "this is what's up, we know it's crazy, but deal with it" and that is actually a good move from MacFarlane. Instead of dwelling on some forced plot device, he just says "take it for what it is."
The plot jumps forward to John's adult life, where he still lives with a now-matured Ted. The bear parties, drinks, smokes pot, has promiscuous sex, and generally facilitates a man-child lifestyle for John. John's girlfriend Lori (the gorgeous Mila Kunis) finally has enough and gives John the ultimatum to grow up and move on.
Family Guy has evolved a lot since the beginning, to the point of becoming something of self-referential parody of itself at times. Ted does walk that line, but just the fact that this is live-action and not a cartoon means MacFarlane can't lean on all of his Family Guy crutches.
I didn't go in with very high expectations, even though the guys from the Free Beer & Hot Wings show said it was one of the funniest movies they've seen in a long time. MacFarlane makes me laugh, I'm never personally offended by any of the jokes. I did laugh out loud a few times, but I also felt like a bunch of jokes fell flat; that also describes pretty much every episode of Family Guy.
