One of the cardinal rules when making a motion picture about a superhero, especially one no one has heard of, is not to make the integrity of the story depend on the existence of a sequel. Unfortunately, that's a rule that director Doug Liman breaks. If the viewer is able to ignore the wooden performances of Hayden Christensen and Rachel Bilson, what's on screen is fine, and even exciting at times. But there's no resolution. Three plot threads are left dangling. Jumper feels like a 90-minute tease. Viewers are left waiting for what comes next and, unless there is a follow-up (which seems unlikely), that dangling will continue for all time. The movie is surprisingly short; couldn't another 15 minutes have been spent fleshing out a few ambiguities and providing the sense of closure that is otherwise absent?
