Diary of a Wimpy Kid

Well I don't know if I would consider the main character wimpy.
But I did think this was an alright movie it would be a good one for kids about the same age as the actors. You don't usually see a movie set in Middle School (or Jr. High which is what they call it where I'm from) they usually have it set in High School but it was a different setting. Now the movie didn't seem to have a lot of humor but there were a few chuckles in there like the scene of the main character Greg peeing on his brother was pretty funny. but other things weren't really like the whole "cheese touch" also what was up with no doors on the bathroom stalls?
one thing is when I'm sitting on the toilet I don't need an audience...that was just weird. also what was up with the "girl from under the bleachers" she seemed to sow interest in the Greg character but he kept shutting her down but as we all know but the end of Middle school he will be wanting all her attention lol. but still I don't see why he couldn't have been friends with her anyway, Greg's friend Rowley was a little bit off and seemed kind of effeminate to me and I was wondering through the films if the character was suppose to be gay and didn't know it yet?
also the crazy kid and the whole booger thing where Greg looked like he was sleeping in the bathtub what times was that suppose to be? wouldn't someone need to get in to the bathroom between the time Greg went in and came out? would Greg's parents be wondering where he is? but with all that said I think it wasn't a bad movie it was kind off lost on me but like I said someone in that age group would probably like this one.
