Juliane Moore gets pregnant without Hugh Grant's knowledge, with him believing she is on birth control and it is her decision to keep it despite any feelings he may have. Tom Arnold's children continually are rude and a constant nuisance to Hugh Grant, and he physically attacks Hugh Grant on multiple occasions. Everyone judges Hugh Grant's character. Why? The screenwriters make him out to be the misguided fool, but he does absolutely nothing wrong. I found this pretty offensive actually.
Anyway, that's aside from the actual movie which isn't really funny and would have been a complete disaster if not for a few funny scenes with Robin Williams and the movie getting decent towards the end when it became all slapstick. Not recommended.
