Given its uninvolving story, uninteresting characters and the presence of half-man/half-tree Hayden Christensen, the movie is wholly dependent on special effects, which I rate only so-so.
Jumper, based on the novel by Steven Gould, re-defines -- downward -- the notion of dreadful. It does so by dispensing with everything a movie needs for a shot at being merely awful.
It's a paradox, but science fiction has to make sense: It can rest on the world's most outlandish premise, but only if its internal logic holds up to scrutiny. And Jumper can't make that leap.
A movie so silly you may find yourself giggling helplessly even as you wish you could magically transport yourself almost anywhere else in the world but where you are, in front of the screen showing it.
Is there something innately vexing about a story whose premise opens the door so wide, to so many geographical possibilities? Jumper, the film, goes everywhere and nowhere.
It's positioned as the first installment of a trilogy and, if Christensen follows through on the character's promise of greater charisma and depth, I'll willingly line up for the next two.
