That's a shame. I'm not a huge fan of Rogen's, but I saw a screening of this a few weeks ago (the first public screening, actually), and it was probably my favorite work of his so far. It's weird to read it framed as "a movie about the assassination of a sitting foreign leader," because it didn't feel that way. Yes, that plot is technically true, but it feels like its just background for the comedy. It's actually very light for most of the time, with James Franco joking around with the leader and learning his more human side.
I don't want to give anything else away. It's just a shame.
