Babies and sentimentality are both pretty gross. And yet, for a movie with both Knocked Up is pretty fucking funny. I saw it last night and I don't think I have laughed at a movie so hard since watching the "Oh are they?" scene from Rushmore for the first time.
That could be because it's got a very amusing script and great acting or it could be because I'm a sucker for an absolute Freaks and Geeks reunion, with Seth Rogen, Jason Segel, Martin Starr and James Franco. Either way it's very entertaining and shows up other comedies in the R-rated vein up as sub-par by comparison.
Plus I would reconsider my no-babies rule for Paul Rudd in a second if the opportunity came up (seriously dude- call me).
