Spoiler Thread: Avengers Infinity War
Just watched it again. Even better the second time. Thanos is such a good villain. He has a plan, conviction and the determination to follow through. It's his destiny.
The gauntlet was definitely damaged at the end. He basically had used it twice with all the stones, once when Thor was attacking (not sure how many stones were involved, but it was a white beam he shot) and once with the snap. And then once after the snap with the space stone to leave.
How are they going to actually find him to attempt any sort of reversal? Apparently Thanos could track the stones, though it wasn't shown how.
