OK so I decided to watch this movie when i received it on DVD a few nights ago and I thought it was pretty decent. Its no means like the original American pie movies (first 3 movies) but its still pretty good. In my opinion, its better than the last 3 spin-offs (those were a joke). Book of love had interesting characters and they weren't really annoying and weird. It also had a few funny scenes, like the opening scene where the main characters does pleasure with a peanut butter sandwich, and a scene with "monique" lol. I had some low expectations about this movie because I've heard some good reviews and some bad ones but I was expecting it to be poor, but I was surprised, it was pretty good. It isn't on the level of the original American pie movies but that doesn't mean its garbage. Although there wee a few weird and dumb scenes. Overall, i liked the movie and it was a thrill watching it.
As a rewatch 04.03.20' and over 10 years since the original viewing. Opinions have slightly changed, as this film is quite poor, really isn't that funny and at many times comes across as forced. The characters really aren't that interesting or memorable, although the lead character of Rob is likeable, he does come off as rather weak minded. The film is watchable and as stated in the original comment, there are some decent scenes as this entry does appear to have more heart in comparison to the other spinoffs. But overall it isn't that great. Rating changed from a 7 to 5.
