The Muppet Movie - Great all the way through. 5/5
The Great Muppet Caper - Again, great all the way through. However, I did find the ballet scene to be a bit slow. But I'm sure that's only because I'm not a ballet fan. 5/5
The Muppets Take Manhattan - Very enjoyable throughout, but not quite up there with the previous two. 4.5/5
The Muppet Christmas Carol - Works better as a Henson production than a Muppet film. A very well-made film, but the Muppets themselves are in more second-string roles. 4/5
Muppet Treasure Island - I'm surprised some people consider this a bad movie. It has the same degree of goofiness found in classic Muppet productions. So what if some of the Muppets are playing 'characters'? So what if several classic characters hadn't been re-casted yet? 4/5
Muppets From Space - Could have been much better if put into the right hands. The only positive notes that come to mind are the scenes with the Muppets Tonight characters, the Gonzo/Rizzo relationship (especially during the ending), and the boarding house scenes (why wasn't a series built around that?). The rats Rizzo befriends are also fun characters. Not great, but still worth seeing. 3/5.
Kermit's Swamp Years - Typical direct-to-video children's film (yes, I would consider this particular production a 'children's film'). It's yet another film that could have been better. The adventures of a young Kermit isn't that bad of a premise. But I really don't feel like enough care went into the finished product. Overall, it feels as though this was made strictly for the kids (hence my using the term 'children's film'). Still, there are some bright moments (namely Bill and Joey as "Croaker" and "Goggles").
A nitpick - what time period is this film supposed to take place in? Everything screams "2002", especially the school that Kermit and the gang wind up in. 1.5/5.
It's a Very Merry Muppet Christmas Movie - I remember when this premiered on NBC way back in November of '02. I liked it. Seeing old friends like Scooter and Janice (along with further exposure of new friends like Pepe, Johnny, and Sal) was great. Seeing the Muppet Theater make a comeback was also great. Overall, a fine film that I still enjoy watching. 3.5/5
The Muppets' Wizard of Oz - It's been awhile since I've seen this one (I don't even think I got through all of it in my last viewing). This is yet another film that I feel could have been much better. Still, I liked the bright, colorful depiction of Oz (even if it's largely green/blue screen), and the various Muppet cameos were fun. 2/5.
The Muppets - A solid comeback. While I was initially worried that the finished product would have "fan fiction" written all over it, I was very happy with what I saw. It's a love letter to the fans, but just as enjoyable for newcomers. However, I do wish a little more thought had gone into the editing of the plot. Keeping in the exposure of Richman's backstory, as well as the backstory of the Muppets' split wouldn't have hurt. Getting rid of Amy Adams' song and working on Richman's decision to give back the Theater also wouldn't have hurt. I also felt the excessive celebrity cameos was a bit much (some of celebrities literally do nothing but sit there). 4.5/5
