I saw it again today, and I'll have to revise my score from 3/5 to 4/5. I still have some problems with the Dominic/Da Vinci Code stuff, and I was even more bummed in that payoff scene when one of the dudes goes, "It's the Muppets... this isn't going to be easy." (just weirdly mean-spirited) The finale, although I love the idea of performing Together Again is somewhat mismanaged with those awful green-screened cameos. I still can't complete Bobin okay'd that to go onto the final print. It's a bad idea and should've been cut in favor of just a clean finale.
However, the rest of it I was able to enjoy more as silly Muppety fun, and it is indeed fun even if the tepid third-full theater seemed to be sleeping through it more than anything else. (Piggy's awesome attack on Constantine finally woke them up, though) I absolutely still adore Matt Vogel's puppeteering and I think he showed up Peter Linz for creating a new Muppet character, even though Walter is still likable. Was able to catch more jokes this time around, and the songs are still awesome (if a little too cut up)... "I'll Get You What You Want" reminded me a lot of 90s Muppet projects, especially MTI which isn't a bad thing. (I had to run to the bathroom during it on first watch) It's a catchy, hip song with clever lyrics, visuals and rats singing in the background. (I love whenever any Muppet projects have the songs "backed up" by other Muppets in the background... it gives you a great subtle sense of the world they're putting you into and just pulls me back into childhood)
Once again Ty Burrell and Sam Eagle are just hilarious, and I even enjoyed the wacky Muppet Show segments a lot more. Suddenly everything started gelling more together this time, although the 2011 movie is arguably still the better "film". I am very glad this got made, and it's enjoyable in its own right as just a fun Muppet movie with lots of good laughs. I mean, it features Beauregard in two scenes... and honestly that makes the movie for me.
