The straight-to-DVD sense.

Trying to remedy the past is a recipe for trouble in time-travel films, but Richie Mehta’s wormhole drama sorely needs a time machine to go back and fulfil its half-baked potential. The Sixth Sense’s Haley Joel Osment broods convincingly as a troubled top scientist trying to finish his mysteriously long-lost dad’s timey-wimey experiments, travel back in time and save him.

But classy casting (Gillian Anderson, Victor Garber) and teasing subtexts can’t fix the logic leaps and longueurs. After umpteen draining chats over blackboard equations, it’s clear something isn’t adding up.
