Perhaps it's a little "too American" to be really funny for a worldwide audience.

Rating: 6/10 (8 October 2008)

I'm not from the US, but I admit I had a few good laughs while watching this at a theater the other day. But there were just these few quite good laughs, probably not more than five. It made me think that the film is a bit "too American", it happened quite a few times when something was supposed to be funny and people didn't take it as such. One good example is the "DVD comment" from Downey Jr., people didn't laugh much, probably because they didn't get it. There are more of these examples, but I don't want to mark my comment with spoiler alerts. Or sometimes people laugh at the accent and not at what't actually said.
A lot of the jokes get "lost in translation" if you are not American and if you read subtitles. The other problem in my opinion is that there isn't a peak laugh, or a really big laugh in the end. Because of that I think a lot of people left the theater a bit disappointed. When I saw such high marks for this film I was a little negatively surprised. It almost seemed to me that I didn't watch the same movie. Some would argue that despite the lack of grand laughs in the end it's "overall" funny, but in my view, more mildly.
