Clint Eastwood directing is amazing. I don't know if he is a great director because of his age and experience, or because he's just that good. If it's the latter, I'm sad he hasn't directed more movies. If its' his age and experience that makes him great, then I'm ok with him being old. It's going to suck when he passes away.
I'm curious how this movie ends.
Also, I would debate "most lethal sniper in u.s. history". Probably 95% of sniper kills are either unconfirmed and/or classified and not counted.
