I don't see how anyone can blame people for comparing MMW against the first film. Aside from Segal, all the same people were behind both films and this one picks up directly where the first one leaves off. They make a big deal about it being a sequel and, with basically the same crew making it, I can't blame critics for expecting more of the same, and then getting disappointed when they got something different.
You CAN blame them for NOT doing the research and realizing that
every Muppet Movie is different and they never (intentionally) made the same piece twice.
Which begs the question...what the heck
were they expecting? You can't follow a big comeback film with another big comeback film. What are they supposed to do? Break up again? Then at the end make up again? Did they want another film where the Muppets needed Jason and Amy to hold their hands the entire time? These reviews were baffling. They didn't even hate the film, they were just mildly disappointed... which again is A MILLION times worse than something that's totally terrible.
We got a different movie, the small quarter of critics that didn't like it didn't like it in comparison to the last film (with a blind obliviousness of the pacing and editing problems that plagued it) instead of the merits of the film for being what it was. And we have some overly influential people that are hanging on those
small amount of slightly disappointed reviewers who somehow never seen a Muppet movie until the last one. Meanwhile, they ignore poorly reviewed trash that manages to make money (cough cough The Nut Job).
IMO that isn't a valid reason of why a movie is bad! If you don't like the voices that's one thing but I don't think they realize how long Steve has been performing Kermit. They act like he just took on the job a few months ago.
Listen... I can understand critics being elitists that hate everything, critics that get rubbed the wrong way by something substantial... but "Wrong Sounding Muppets" is the
dumbest complaint about this movie. Like they weren't "wrong sounding" in the last one. I've lost all respect for movie critics. I really have.
