It's because Jerry came out against the left and "PC crap" that so many outlets are condemning him and his film. The film itself is light, silly fun. There's not a mean bone in its body (though there are a couple of great dark jokes, one involving a ventriloquist dummy and one involving Steve Schwinn), and certainly no partisan bones. It was made to be, and successfully is, light entertainment. There are no large-scale "messages," even including the Jan. 6th joke, which is played for laughs rather than ideology. It shouldn't offend anyone unless they turned it on expecting a genius level comedy on the order of Dr. Strangelove. It's not that, and it wasn't meant to be that, so expecting it to be that is stupid. It's just an old-fashioned fun time at the movies...which, sadly, people seem to have forgotten how to have.
But it's true, Amy Schumer is terrible and she's the worst part of the movie. On the plus side, the rest of the cast kills it. If someone would've told me beforehand that Bobby Moynihan would be the funniest part, I would've been extremely skeptical, but I laughed literally every time he was onscreen. Hugh Grant was also great hamming it up. And Max Greenfield is always hilarious as that ball of obnoxious energy. It's goofy and it's campy, but it's fun for anyone who remembers how to have it.
