Adam Sandler still shows up for a movie looking as if he just rolled out of his trailer. Let other actors fuss over their wardrobe or worry about whether they’ve gained a few pounds: Sandler is Sandler, the people’s noble-slob comedian! Mr. Deeds is one of those Sandler opuses in which he plays a big-hearted, happily dysfunctional ”normal” guy. An idiot variation on Frank Capra’s ”Mr. Deeds Goes to Town,” it’s a tossed-together exercise that feels sort of like the dumbest corporate comedy of 1987. Every so often, the star lets out his id by punching someone into the ground, ”Happy Gilmore”-style. All in all, though, this is Sandler running on empty, repeating what he’s already done far too often.
