Everything is going ok, not great, but ok, until they manage to disable the aliens' shields and you see what they look like. Those things look comical and you get a flashback to that new Star Wars movie where the menacing "new" Darth Vader clone takes off his mask and reveals a huge nerd looking guy underneath and you can't help but to yell "PUT IT BACK ON!". Also for a huge intergalactic menace you'd expect and think it would take more than some guy throwing a rock at them to kill them...but what do you know....
