People falling or being thrown great distances and they get up without effort has immediately crossed into the fantastic. After that it's nitpicking to belabour other elements asking for suspension of disbelief.
Ah, but most action movies where heroes survive totally un-survivable beatings have the good sense not to have scenes in which doctors tell them how wrecked they are. Tony Stark takes far worse hits than Nolan's Batman, but you'll never see a doctor tell him
he'll barely be able to walk again.
