Amazing ricochets in the final showdown *spoilers*
I couldn't stop cringing at the ricochets. You'd see one rock explode, and then a second rock would explode right after it. Fantastic effects. Probably scientifically "slow", but aside from that, I was mesmerized. I don't think I've seen anything like it. Such a small detail, but it made their positions in the rocks seem a thousand times more dangerous.
Usually, I wonder why people shoot at "nothing" in movies. But here, they had a good chance (and did) of hitting each one or another by bouncing those bullets off what would otherwise be a good hiding place.
