Garrison Keillor, Meryl Streep, and Lindsay Lohan in A Prairie Home CompanionA PRAIRIE HOME COMPANION

One of the many glories of Robert Altman is that he never pretends to know everything there is to know about the characters in his movies, and doesn't expect his audiences to, either. In an Altman film, you may think you have someone all figured out, until a later scene proves that you haven't begun to understand what makes them tick; Altman is fascinated with the dichotomy between characters' public and private faces. (It makes perfect sense that he eventually filmed a murder mystery.) It sometimes seems that there's not much going on in an Altman movie, and audiences could easily assume the same about the director's latest, A Prairie Home Companion. But if you're as enthralled with character as the director is, and with the drama of actors gradually revealing character, his ambling, "plotless" films can be sheer bliss.

Charlize Theron in Aeon FluxAEON FLUX

By all rights, Aeon Flux should be godawful. (Certainly, Paramount is treating it like it is, as the studio opted against pre-release screenings for fear of lousy advance notices.) Set some 400 years in the future, director Karyn Kusama's film - a big-screen vehicle for MTV's Liquid Television character - takes place after 99% of the earth has been eliminated by a virus, the most humorless 1%, apparently, having been left to roam the earth. Charlize Theron's Aeon leads a Spandex-clad revolt against the government, and the movie is, for the most part, a joke; the effects are particularly shoddy, and as they recite their clunky dialogue, you feel badly for several performers - when they were being feted as Oscar nominees, did Theron, Frances McDormand (in a red fright wig), Sophie Okenedo and Pete Postlethwaite ever think it would come to this? (The film's one impressive performance comes from Marton Csokas, who's like a more rugged version of Kevin Spacey.)
