If you're going to use stick figures, then it has to be EXCELLENT animation. When people see Stick Figures, they automatically assume it's not going to be the best movie. So if you're going down the path of no faces, be sure u have some of the best action sequences of all time or the movie's not going to last long.
If you're gonna try to make a story that goes along with the action, then I suggest putting faces on the sticks. You can show only so much emotion with gestures. You need their faces to show anger, worry, stress, happiness, etc.
otherwise this movie was OK. Not the greatest but not the worst. The weapons, helmets, and the plane were decent. though the action and the basic story of the movie moved waayyy too fast and all I could remember was Zack saved Jim.
