Having just seen this, I can't agree with the majority of negative votes. Granted, it is a low-budget movie with no star power and a we-have-seen-this-1000-times-before script. But with the limited resources they had, it is an enjoyable sci-fi action flick. IMHO the actors played their parts convincingly and the action was okay. The only really bad thing about this were the CGI shots of the portals... that looked like from a 90s computer game.
If you have some time to spare, give this a shot. There are far worse movies out there.
