Wings: Sky Force Heroes

I don't really know what's so great about this boom, when the main characters are animated planes. What's so interesting about them? Especially when they are drawn so strangely, like in the movie "Wings: Sky Force Heroes". The ending is fine, it tries to be action-packed and suspenseful, but otherwise it's just reheating something that has already been reheated several times. (10/10/2014)
