Adewale Akinnuoye-Agbaje and Kit Harington in PompeiiPOMPEII

About a half-hour into Paul W.S. Anderson's Pompeii, the film's protagonist - a gladiator-turned-slave amusingly named Milo - hears the unfamiliar sound of the nearby Mount Vesuvius preparing to erupt. "It is the mountain," says Milo's comrade Atticus. "It grumbles from time to time." So do movie reviewers, and this latest 3D action spectacle by the director of Mortal Kombat, Death Race, and a trio of Resident Evil flicks would, at first glance, appear to be exactly the sort of thing I'd personally grumble about: a predictably corny, derivative, overscaled costume party with loads of generic violence and nothing in the way of subtlety or emotional nuance.

Yet while it's easy to name the movie's most direct influences, Gladiator and Titanic chief among them, what I didn't at all expect was for this swords-and-sandals outing to be so thoroughly, cheerfully indebted to 1970s disaster epics in the vein of The Towering Inferno and The Poseidon Adventure; Pompeii, to its cheeky credit, is kind of like 1974's Earthquake with the ancient Roman city cast in the role of Los Angeles.

Dwayne Johnson in G.I. Joe: RetaliationG.I. JOE: RETALIATION

If you handed a box of crayons to a group of eight-year-olds with action figures, they'd probably come up with a more entertaining storyline for G.I. Joe: Retaliation than the one we're stuck with, which is your standard blockbuster nonsense about a megalomaniac's plan for world dominion and the crack team of well-armed, quip-ready hotshots attempting to thwart him. In a welcome surprise, though, director Jon M. Chu's follow-up to 2009's G.I. Joe: Rise of the Cobra is, unlike its forebear, quite a bit of zippy, throwaway fun, a fast-moving and happily unpretentious diversion with jokes, and good ones, obviously written specifically for viewers well over the age of eight.

Russell Crowe in Robin HoodROBIN HOOD

With director Ridley Scott's heavy-spirited adventure Robin Hood, the audience waits nearly an hour for its first reprieve from the grimness and grime, and when it finally arrives, the moment consists of Max von Sydow's blind land baron getting a whiff of Russell Crowe's gamy Robin and growling, "You stink." As mood lighteners go, so does that gag. And so, for the most part, does the movie.

In discussing this year's Oscar races in the picture, director, and the acting categories, we may as well begin with the nominee area audiences had the least chance of catching, as it was the only major contender yet to get an area release: Duncan Tucker's Transamerica.
