Just to give a better description though if anyone might stumble across these films - they aren't actually badly produced or owt, they're just churned out so much just for the money that some things really suffer; most notably the script. For some of em it seems like the scriptwriters were just so chuffed to have finished they refused to even re-read the script for continuity, even once.
The whole cast can even change halfway though.
They are made so much solely for the cash that they are generally rip-offs from genuine sci-fi films - half the reviews on imdb are from people pissed off because they were fooled into thinking the film was the genuine article rather than the rip off. One dude called C Thomas Howell makes a lot of these films; scripts, directs, stars in. But the thing is he just looks like he can't be arsed being there - he's ace!
One other thing, these films are obviously best enjoyed wrecked, preferably obviously a sativa
Just so no-one thought we just laughing at stuff just for being shit, cause that's just a bit shit
