I would say that 50/50 is a really good dramatic comedy, but it's not the best film you'll ever see. You'll appreciate the male performances and the plot as a whole, but there will be moments where hte pacing feels off and you'll get annoyed with the females. I would wait for DVD, unless you need to see a film. And In Time, I agree, doesn't need to be seen. I would say Cillian is the only reason to see it.
