I've gotta say, I really loved the first Muppets movie. Considering it was all about how the Muppets can still be relevant in the current times and everything.
Also, did anyone notice the first movie was just a metaphor for the relaunch of the Muppets? I mean, the main character who brought the Muppets back together was called Walter. Walter? ....Walt? Like in Walt Disney? Because Disney made the movie? And Jason Segall was a character AND the producer or something. So, yeah, the whole movie was a metaphor.
Considering the trailer also makes fun of the fact that it's a sequel, you can tell they're going to break the fourth wall as much as last time. "Why don't we just travel by map?"
