Probably one of the weakest spin-offs. The premise of finding the "Book of Love" (the sex bible written by the protagonists of the first movie) had potential to connect with the original, but the execution is pretty poor. The jokes are increasingly crude and less clever.

Flat humour, little charm. Only for fans

I have a random softspot for this movie, even if I know its bad. ETA fourth watch: I've realized what specifically I like about this one. It feels more ensemble than the other spinoffs before this one because there's three guys with their own story, and the girls they're involved with feel a *bit* more like people, plus the Stifler in this and Imogen get their own mini-arcs too. This makes it feel more ...Pie...ish than the others. The disposable sex worker stuff (that is probably the favorite scene of the core audience) is kind of hard to justify but the rest of the film is fine. Most of the performances are acceptable. Seeing Beth Behrs pre-2 Broke Girls is fun. I also like the... coloring? In this. Its brighter than the Naked Mile/Beta House duology.
