The barely lit image of a man’s emergence from a pool of primordial sludge launches one of the decade’s most audacious and sophisticated science-fiction films. French director Franck Vestiel keeps the audience as bewildered as his unnamed hero while the figure makes his way through an environment that looks like the complex in Aliens with a bad infestation of creeping bent. That the final revelations can’t quite fulfill the expectations created by the beautifully cryptic and satisfyingly intense early scenes does not detract from Eden Log’s overall effect or heady allure.
