In most movies about dumbasses, the dumbass has an epiphany that makes them stop being such a dumbass. Not in “The Wrestler” (2008), which is about a dumbass wrestler. It’s more like real life: dumbasses pretty much stay dumbasses forever, doing the same dumbass stuff over and over, with occasional forays into virgin dumbass territory. I liked it. Speaking of virgins, Marisa Tomei is very naked in this movie, belatedly answering prayers of now-middle-aged men who wanted to see her naked when she was doing chick flicks like “Untamed Heart.” Not mentioning anyone in particular. He’s probably just a dumbass.
