^Well, it could have been even nicer if it could be activated at any time. Say I die 8 times right near the end of the level, watching the demo of everything before that is quite useless.
Also, I hope that levels beat by the "helper Luigi" count as beat for Mario.
All in all, anyway, it's a good feature. And yes, "game over" was already useless in SMG and has to disappear the way of dodos.
