Bulletproof horses
Supposedly these farmers can't hit the broadside of a barn yet every attacking rider gets shot off of his horse cleanly. Then the Gatling gun opens up while men are still riding around through the town and still no dead or injured horses. I guess that the horses of the men next to the Gatling were vaporized by that stick of dynamite. Did anyone see a single horse corpse among the piles of humans? This seems to be taking PETA movie standards to ridiculous levels.
