Here are my (very) quick reviews.
Nacho Libre is very funny at times, but not a classic comedy. In a number of instances, I felt that Jack Black was a bit too… Jack Black. The end of the final fight was great though!
I was a bit concerned that Talladega Nights was going to be a Will Farrell vehicle (like Nacho Libre for Jack Black), but it never really descended into that. It was surprisingly good and very entertaining. Sacha Baron Cohen (Ali G, Borat) plays the villian and he complements Will Farrell well.
