I could be considered an amature at best and i gotta say that that guy looks like he sucked.
A) he didn't have his guard up and charging right into a fist is generally discouraged. He should have been able to do an esciva (or however it's spelled. I've not done this in a long time) to dodge said punch and respond with a kick easily.
B) attempting to showboat when you haven't earned the skill needed to pull it off and not get your ass beat down is discouraged.
C) upon further examination of the movie he actually jumped after the punch was started so he should have seen it coming and he simply completely and utterly fucked that up. I at least thought at the start that he was punched before he landed but he was trying to do fancy bullshit when at least 2 basic maneuvers would have saved his ass.
