Tim Robbins, Tom Cruise, and Dakota Fanning in War of the WorldsWAR OF THE WORLDS

My first thought after seeing Steven Spielberg's War of the Worlds was: Thank God for the aliens, because although the creatures themselves aren't particularly memorable - a gooey blend of the director's beatific Close Encounters visitors and H. R. Giger's 1979 Alien design - their spacecrafts certainly are. The ships' enormous tripod legs, crushing everything in their paths, exude a wriggling, snakelike suggestiveness, and they have vicious talents besides; these tentacles have the ability to either incinerate their victims instantly - making the human race resemble ants at the mercy of a magnifying glass - or toss them into the spaceships' grotesque "mouths," producing more grisly, prolonged executions. (A couple of killings are reminiscent of Steve Buscemi's demise in Fargo.) To the War of the Worlds aliens, humans are a combination of entertainment, nuisance, and snack, and whenever Spielberg gives us evidence of just how queasily horrifying an attack of this nature might be, his movie is gripping and evocative.

My second thought was: Steven Spielberg has lost his mind.

The Day After TomorrowTHE DAY AFTER TOMORROW

Despite all the hullabaloo about the film re-opening vociferous debate about global warming and its possible effects, Roland Emmerich's disaster saga The Day After Tomorrow winds up begging exactly one question: Just how much stupidity are mass audiences willing to accept in their summer blockbusters? In any disaster movie, rolling your eyes at the ridiculous onscreen events comes with the territory, but the enjoyable ones temper that reaction with speed and laughs; Emmerich's cheeky, entertaining Independence Day managed the feat of making the end of the world look like an absolute hoot, and that film, within its sci-fi format, is probably the most sheerly pleasurable disaster flick of the past 20 years.
