Well Alien may be a bit of stretch, when they look exactly like us (even with breast implants - looks like these things are chic all over the universe). Like the other two movies I watched (all from the same director) this does not try to fool as to what it is. "Solid" story (rock solid?) Hard as a rock? Wait the last one does not make any sense ... well not in the conventional way that is) - one might say. With many comedic elements like Agent Smith and Agent Jones - I'm looking at you guys - though mostly at the female of those two, very pretty.
The freeze taser/gun is sort of fun, the low budget (no budget) has everyone acting like they are frozen, while they blink as if their lives depended on it. But if you leave that aside, this is softcore to the ... core? I don't know, but what I do know, I've seen enough of these for a while now ... not to mention there are so many, it would become a life goal ... well nope, as fun as they can be, even or rather especially if you just watch the story (which makes them also quite short - no inuuendo or pun intended here)
