I enjoyed The Muppets as a lifelong fan and admirer. I can see how some people can have some issues with the movie. Honestly speaking, the voice and mannerisms of Piggy didn't gel well for me. I think there is much room for improvement to bring her back to the Piggy we all know and love. Fozzie was inconsistent, sometimes sounding great and sometimes sounding not so great.
I think people may have trouble with an unknown character like Walter pushing tried and true classic characters like Gonzo out of the picture, making people think, "What am I watching? This isn't the Muppets!" I was also a little bothered at where Kermit lived and what he had become. He would have moved on to bigger and better things, staying active, maybe working behind the camera or working on other projects, not becoming a recluse or a museum piece. It was sad and I didn't want to accept the fact that the Muppets would break up and dissolve due to becoming irrelevant.
I will tell you though, I almost cried when they replicated the opening to The Muppet Show. I had goosebumps running up my arms. It was so amazing to watch. They REALLY did a great job with that part. But I also think it's time for the Muppets to part ways and move on from the likes of Whoopi Goldberg and find some new talent. She's too controversial and alienates half the fan base with her wacky political diatribes on The View. Keep politics out of the Muppets! The Muppets also needs to be Jason Segel's last muppet movie. I really don't want to see the Muppets become all about Jason Segel.
The movie was so intriguing being written from a muppet maniac rabid fan point of view that most of us can relate to, not to mention the freaky muppet dreams of them coming alive and meeting them all. That's where I really related to the movie. I can't tell you how many dreams I've had of meeting Jim Henson and getting to work with him and it feeling so real! So while not classic Muppet material through and through, it was still really enjoyable and where it falls a little short can be forgiven.
