Disappointing that total stupidity is considered funny

Rating: Null/10 (18 October 2011)

Maybe its just me that I'm getting older and not finding certain things as funny anymore, but I have to say this was a bit of a disappointment.
For the start I was enjoying it, but the character Dale really started to ruin it for me. First he rejects the sexual advances from Jennifer Aniston which is simply crazy, but that's part of the theme for her so its cool. But his completely stupidity really starts to irate me to the point I just don't want to watch it anymore.
I'm beginning to wonder if its just me that thinks the factor of being totally stupid isn't funny at all. Its just if you get an education to be dental assistance you think you'd be smart enough not to do so many stupid things. They could've changed the script slightly to make it funny without making him seem like hes still 12. It really ruins the movie for me and I ended up skipping from about an 1hr or so in until the end. But if you don't mind that element in the movie then you'll really enjoy it as apart from that I liked it.
