CB: 50/50 opens this weekend, and if you've read Eric Eisenberg's glowing review, you know he's fully in the tank for the comedy-drama starring Joseph Gordon-Levitt and Seth Rogen. Now normally when you get a movie released in the fall about a main character who gets cancer, and when the critics falling all over themselves to praise it, you get oodles and oodles of Oscar buzz. But 50/50, a drama with heavy doses of comedy related to drugs, girls and other tawdry things that interest 20-something males, isn't exactly the kind of movie that automatically gets invited to the big awards show.
