Reiterating: I never finished watching the movie, and what little I managed to watch on TV was years ago so I can't say I remember everything perfectly, but I don't remember laughing a lot while watching it.
And the moments I did laugh were not because of "haha, look at this loser, he has a doll for a girlfriend" kind of jokes.
It's not Adam Sandler humor.
I don't know if that was your concern? Maybe I'm reading you wrong :P
I'd say if you found it even remotely interesting just give it a try :)
