Adam Sandler's Happy Madison Productions is the perennial pop-culture zombie that refuses to die and wants to eat your brain. In this, their latest creation, Frank Coraci directs former Zookeeper Kevin James as Scott, an unlikable schlub who accidentally volunteers to save the music program at the high school where he teaches. So of course he figures that the only way he can come through with the money is by competing for cash in Mixed Martial Arts bouts. Need I tell you that he's an out-of-shape lazy biology teacher? Apparently, this is when the hilarity is supposed to kick in, but all we get is the same physical comedy from James's repertoire and overused Sandler-esque jokes. Henry Winkler co-stars as a doting but dumb music instructor, and Salma Hayek is the love interest whom Scott woos with sexual harassment. Maybe you'll enjoy the bits of Boston that make cameos; otherwise you'll probably find Here Comes the Boom to be more like a fizzle.
