To be fair in Amazing, his mask was pulled off by the lizard and in the other scene there was a narrative reason for him to take it of. It wasn't just for the hell of it. In the first three I have no idea why he took the masks off minus the one time where it was fried and potentially burning his face
True I only seen the new flick once at the theater when it first came out and saw bits and pieces of it on Starz at my Mom's crib when it came on. So i'll probably check it again before I see AS2.
