Two comments:
1. If this is really about a minute and a half of footage, for $5, you might want to take a look at Project Super Woman for comparison. Longer videos for close to the same price.
2. the use of superbreath itself is pretty lame. They don't appear to be blowing very hard. There's more to trying to blow someone off of a roof than just puckering up and then having the special effects try to do the real work for you
