I just got back from seeing this movie, and I have to admit that I really enjoyed it. Possibly because I wasn't expecting to, but I also wasn't against giving it a chance. To me, the commercials did not look very promising, and when it was compared to the hangover in one ad, I really wasn't expecting much. First of all, when I went to see the hangover, I was ready to laugh like crazy due to how funny everyone said it was. Personally, I didn't find it very funny at all and I always felt the writers/actors were trying too hard make a joke out of everything. The only thing that kept my attention was the semi-interesting plot.
I found the ads for She's Out of My League to be promising a "hangover clone" (in terms of the type of humor). Thankfully this movie is not what it appears to be. Many will disagree, but I felt that there is more reason for watching this than for a constant need to be funny and outrageous. I also liked the character in this movie, and found they added a lot to the story.
Although this movie offers nothing we haven't seen before, I found it at least to be enjoyable. Another reason I liked this movie is because I felt there was a storyline that made up for most of the jokes I didn't find funny.
I know that most will find it to be a pointless movie (and I guess it is to an extent), but I found it to be entertaining and worth seeing. I'm glad I wasn't expecting to be laughing throughout the whole movie, because I didn't, and because I found it to be a little more than what I was expecting from the plot.
