Heck, I'm not a "Big Bang Theory" fan but I **** when I saw Parsons in the film, simply because he was the PERFECT "human Walter." It was the choice of casting, and the way Parsons delivered his songlines, that made that bit work and work hilariously.
And yeah...NPH's little asides were funny. I'm not really a Jack Black fan either, but he interacted fairly well with the Muppets throughout. (I love the scene between him and Animal at the trailer -- right up to the bad CGI, anyway!)
