What kind of an organization the Paladins? as they have previously worked (without technology?!?)? Why is the mother, and why can not they get out? How many jumpers are there? Above all, the problems with the mother could have broach more, also their inner conflict and perhaps a decision moment. But it will only scratched the surface: Short, meaningless 1-set conversations without much emotion. And the sister at the end, where does the come from?
At least the actors are well chosen: Hayden Christensen, Rachel Bilson and Samuel L. Jackson one looks like to. Kristen Stewart is also very good to see it you could have done even more. The effects are well done and not look cheap - after all. But the nonsensical story may thus not be saved.
Overall: Nice theme, looks good, but oh well ... Story
