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.
Pretty much it. You can't have it both ways, you can't in one scene tell me that Bruce Wayne has no cartilage in his knee rendering him crippled for good and then, later show him using a crazy leg brace to kick rock walls apart (which still wouldn't overcome the pain and problems in his knee) and then even later show him doing push-ups and other calisthenics withgout the crazy knee brace and THEN show him fighting and holding his own.
Because those things do not flow. It's an increasing series of contradictions. We were told in the beginning of the movie that Bruce Wayne for all intents and purposes was crippled
but he just somehow "overcame it." So either Billionaire Bruce Wayne went to a REALLY shitty orthopedic doctor or the movie has a plot hole in it.
It also renders that whole plot point sort of useless if it's just shrugged off.
