WHAT DID YOU EXPECT, WE'VE SEEN HIS GIANT HANDS: We probably need a thread for spoiler discussion of Forgetting Sarah Marshall, which I highly recommend. In a lot of ways, it's more human than Knocked Up and Superbad, particularly on the female side. Sarah Marshall is a fully formed character rather than just being either an unattainable beauty (Superbad), or a shrill nagging harpy (Knocked Up). Lots of very funny people doing very funny bit moments (Bill Hader, Jonah Hill, Paul Rudd, Jack McBrayer, whose story doesn't really connect into the rest of the film, and an ALOTT5MA fave who shows up during the credits in a preview for Sarah Marshall's next project), and Billy Baldwin doing a priceless goof on David Caruso as the lead of Crime Scene: Scene Of The Crime. Jason Segel also proves that yes, he can carry a movie on his broad shoulders and you don't think of him as Marshall even once (and yes, as is obligatory to mention in all writing about the film, we do see all of him--no reciprocation from the female characters, though).
One thing that does bug--Mila Kunis doesn't really work. She looks kind of like a plastic anime doll, and has a weird inflection in her voice that bugs. More significantly, while she's pretty, she doesn't bring any spark or interest to the character, who just winds up flat and not really a match for Bell's smart-ass attitude. I wonder what a sharper actress could have done with the part who could have brought some snark to it--say Amber Tamblyn, Rachel Bilson, or Emily Blunt--could have elevated what's already a very good movie to a great one.
