If cool ideas or concepts would be the only indicator or rating barometer, we would talking a whole different ball game right now. But we are not, because the execution of said idea should at least be good too. Talking about good and involving anything that is shown in this movie would be a travesty. I can't judge the actors by one performance (or rather I don't want to), but they're not really helping the case delivered with this movie.
Don't get me wrong, the whole thing is half hearted at best. The script seems to be incomplete, the characters are shallow at best and the twists are funny, if you're good humored. The effects could be called OK I guess, but only by very low budget standards. In other words: You can smell the CG miles before it hits the screen. If you can't watch things like that, don't even bother. A shame, because it did sound interesting ... which brings us back to square one!
