I heard a lot of negative nattering about the Due Date trailer on Twitter, and I sort of don’t get it – the trailer is so middle of the road that I can’t believe anyone dislikes it enough to even bother typing out 140 characters. It’s the kind of trailer that makes you just go ‘Oh, that exists,’ and then move on.

If Due Date works at all it seems it’ll be due to a Herculean effort on the part of Robert Downey Jr. Zach Galifianakis stars alongside him as an omnipresent comedian who shouldn’t be this famous.
