Most hilarious part for me.......
... was at the end when scientist man, after showing how intelligent he is for the entire movie, is then given one job to do to kill the baddies, pull the plugs then throw the lever, there's even a little animation that he watches showing what to do, but what does scientist man do? He pulls the plugs and then screams "It's not working!!" and then the woman has to remind him that it was a 2 part process and he still has to throw the lever. What an idiot. I guess they threw it in there for tension but it just made him look like an imbecile.
This just after he made a couple of dozen identical looking highly polished space ray guns out of old cellphones and video equipment.
Hilariously bad ending.
