I had a bias against this flash, and I'll explain that in a second. The idea was "fun". These dumb ass big momma's house movies HAVE TO STOP. I'm glad some one is making fun of it... The movie was a bit drawn out and I was fairly bored about half way through. Now, going back to my bias. Gun's have triggers that cause a little "hammer" to hit the primer of a bullet. The primer ignites the gun powder inside of the casing of the bullet and the lead tip fire's out of the barrel. In your video, the casing of the bullet travels with the bullet... I get annoyed everytime I see this.
Bias' aside, I think you did a decent job.
