Well the aliens were not what made the ship they were cargo? A bio weapon kinda made sense But absolutely everything you said makes sense. The movie was shit. I need to rewatch the thing to wash the memory of that shit movie go away. Those aliens can take out tanks somehow? Skin made of what? What organic material can stop a desert eagle .50 cal from 30 feet away. So much stupid shit in that movie it would take 5 pages to describe how bad it was.
