I agree with the above. One of the first bits of advice I got as a new FO on type was to stop attempting to correct every perceived attitude or flight path change with sharp control input.
I slowed everything down and let the aircraft "ride" the bumps without trying to immediately correct every tiny deviation, and immediately a far more stable, comfortably flown approach ensued.
Edit: I'm not making specific comments as to this guy's approach as there's nothing worse than someone sitting on a couch telling you how much better they would have flown it. But in general I think there's a tendency to overcontrol in these conditions, I certainly used to, and maybe still do when the heat's on.
