A disgraceful display of unprofessional, dangerous airmanship.
He sideslipped the aircraft, exceeded Vfe by more than 20 knots, landed with only FL10 (instead of the usual Fl30 or FL40), ignored the F/O's callouts, set up a dangerous sink rate close to the ground, made no report ot the ground engineers of having exceeded max flap speed - the list just goes on and on.
There is no place in aviation for an individual displaying this sort of irresponsible, dangerous behaviour.
His licence needs pulling right
NOW - permanently!
