When teenage genius David Raskin and his sister Chris are rummaging through the attic, they discover a video tape made by their father on the day of his death ten years ago. The tape seems to show current-age David in the background, which leads David, Chris, and their three friends to build a time machine.

Based on the trailer, I thought it was a fun premise with promise, but in the execution, the movie couldn’t decide what it wanted to be: David Raskin, Boy Genius (and scientific hand-waver), or Ferris Bueller and the Time Machine, or The Blair Time Travel Project, or maybe The Butterfly Effect IV. Whichever it was, none of the different directions could support a plot for me, none had a consistently worked-out model of time travel, and none had reliable continuity in the filmmaking.
