We just watched this movie today and all three of us agreed it was a waste of time and money. Yeah! it had its moments of laughter but most of the time it was bad acting (humans of course). To be honest I enjoyed earlier Muppets movies far more than this one. Maybe it was the fact that they had less human - Muppet interaction. Maybe because there was no human-Muppet hybrid for no good reason. Maybe I'm just too old and expect too much but, when I look at my almost 12 year old son I see that he liked the earlier movies better than this one. If this movie was meant to be for younger generation to familiarize them with Muppets and show them how fortunate we "the old people" were to have The Muppets then, I must say the overwhelming singing and dancing killed it right on the spot. To me Segel's character was spineless. It was Walter's character who drove everyone except Segel and Adams to accomplish something.
Someone else wrote this about this movie: "In the earlier efforts, human actors were essentially supporting players. The filmmakers had enough sense to let the stories unfold from the perspective of the Muppets, all of whom were allowed to develop as characters. This is not the case with this film, which gives ample time to Segel and Adams. They play Gary and Mary, a wholesome, sunny couple from the all-American hamlet of Smalltown, where the population number on the welcome sign fluctuates due to the buses crossing the city limits. Much of the film is spent on their being deeply in love – and, of course, on the circumstances that test their emotional fortitude. We know right from the start that their relationship is silly, but the real problem is that it's also unnecessary. It doesn't help that neither Segel nor Adams gives a noteworthy performance. Adams in particular is surprisingly out of place, spending most of her time mugging girlishly."
For me personally the Muppets didn't make a come back they just made it harder to accept them in the future even though I'm pretty sure Disney people are going to shove it down our throats in the near future.
