I used to buy a Leonard Maltin movie Guide every other year or so. He is one of the only reviewers that reviewed Caddyshack2 higher than the original. It kind of starts with the premise that Caddyshack was more of a disjointed series of vignettes rather than a cohesive movie and I do believe there is some truth to that. Caddyshacj2 really had no redeeming quality, so I am not sure how it got a better rating.
HG2 was pretty terrible, and I am pretty agreeable to very inane and silly movies. Abrahams and Zucker movies (Airplane, Top Secret, Naked Gun, Mafia, etc) are things I can watch anytime. I like Farley Brothers, Coen Brothers and Tarantino as well. HG2 had one good gag (Zalatoris). The whole Daly thing makes no sense. Happy is destitute but somehow Daly live in his garage. Bruce might be the stiffest thing ever shown on film.
Cameos can be fun but they can't be a movie. I will say that is I didn't know that was Julie Bowen I would not have recognized her. It is good how Sandler takes care of his buddies some that need it and some that don't. Dan Patrick and Steve Buscemi are interesting friendships. You understand the Schneider, Lovitz, Spade and other SNL guys but the Nick Swardson, Blake Clark, Jonathan Loughran, Allan Covert. He must be a good dude.
