50% isn’t exactly “they hate it”. Especially when you take in genre consideration, about 25% of critics just plain don’t like whacky dumb guy comedy, so the rotten score pretty much ceilings around 75. Of course I also don’t like that style of movie. But I do like honesty. And in a world where there’s 2 movies out in the 20s 50 is clearly not “they hate it”.
I think the reviews seem about right for this kind of comedy, it amused many of us who watched it with no expectations, and half the critics agree, and the more snobby the critic, of course the more they dump on a goofy comedy that doesn’t have the critics in mind.
As far as this stuff goes, it was better than average for the crude Rogen/Ferrell type humor.
