I’m pretty sure American Reunion is a bad idea, likely to lead to a bad movie. I mean, considering that this series has already released a bunch of straight to video films, how can I believe that this is anything but a somewhat desperate attempt from a bunch of people to revive more successful days? Considering that the third movie was clearly already meant to be a final outing, what makes this one any more of a “last”? And doesn’t the fact that they had to go back to a gag from the very first movie show that this is a series that ran out of steam a looooooong time ago?
That said, this is the movie, and all the advertising people can do is work with whatever material they have. And this is a pretty good example of doing that. They created a simple, clean and clearly identifiable image that makes us think of the best moments in the series. Can’t really ask for much more than that.
