This film got better as it went along. Very funny and another enjoyable sequel. The Greg (a.k.a 'Gay')/ Jack relationship hits new levels with a punch up which is very amusing and adds a bit more action that the other films didn't have.
The negative of it is that Greg's parents (Dustin Hoffmann and Barbra Streisand) aren't in it much, as I think that would have made it a better, funnier film. However, this is compensated by the introduction of Jessica Alba, who is actually quite funny and gets semi- naked, which again, adds something the other two didn't have!
Overall, this is a very funny film that lives up to the high expectation the first two films set, which is a very good accomplishment. I would recommend it to anyone who enjoyed the first two films.
