Hilarious in example sentence
The action of the characters is hilarious, from the hyper-dramatic way they fall to gunfire, to their incredibly bad acting (were the bad guys all just pulled off the street, or were they actually actors?), to incredibly bad delivery of lines, to their inexplicable actions (if you are going to try and shoot someone through a doorway as they enter, obviously the thing to do is shoot directly at the doorknob!!).
