You could have called last year’s The Hangover a bit of a comeback film for Todd Philips, since it was his first true hit since Old School. I think it also raised expectations a bit for the follow-up.
I can say that Due Date is a bit of a step-down from The Hangover in terms of being a laugh out loud comedy. That said, this is a different type of film that draws from “buddy road comedies” of of the past with Robert Downey Jr playing the straight man (ala Steve Martin) and Zach Galifianakis playing the buffoon (ala John Candy).
The film features a series of comedic scenarios, some which work more than others. However, there at least two absolutely hilarious moments.
Overall, I would say it was a decent film.
