I will fail this film for on reason only: it was conceived as a TV show pilot and it failed, so they released it as a movie. That means ending with a huge cliffhanger and explaining nothing.
Not everything else was cool, either. There were some clear TV like story fixes and the classic "I am here, I have all answers, but I am going to go because I have important stuff to do" trope, as well as some poor scripting.
However, the rest was OK. Acting was reasonable, direction and special effects, too. The scripting left a little to be desired, but not much.
Bottom line: a clear rip-off of Sliders. At the end of the film you are left with the same premise: "you can't ever go home, but you can always try". The characters, though, are some kids with no training or experience (except punching people for one of them). If this would have been taken on as a series, I would have watched it, but then again, I watch all kind of crap.
