In both those stories, Wayne was old and had been Batman for many, many decades. This Wayne hasn't been Batman for near as long nor been through near as much. Don't forget, the Joker card at the end of BB means TDK happened almost immediately after. So after Joker, he retires for 8 years, which means no physical damage during that time, then comes back for a few months as Batman before quitting again.
Not the same thing whatsoever.
Yes, its is. Cause of retirement; body reached its limits. Beyond is through age. TDKR is through injury.
Now, you need to then ask yourself. Beyond happens when bruce retires through age. Which means every story is night on happened before his old age.
That means he has survived and had zero residual wounds or lingering injuries from any of the stories you want to try and make a canon out of.
Do you REALLY think a human being in peak physical fitness could fall 4 stories, get shot countless times, stabbed, beaten, buildings fall on him and just push them away with a broken arm which magically leaves no residual effect?
Exactly. Your applying comic book logic on screen. It doesnt work like that. BB/TDK/TDKR is one story arc covering 16 years 7 months. Begins happens over 7 years. Bruce returns. However long BB is. The bridge between BB and TDK is 1 year, making it 8 years. TDK is however long, say a month. Then its 8 years between TDK and TDKR. TDKR is covered by 6 months meaning 16 years and 7 month or whatever.
He is actively batman for over a year before retirement, then he is back to being batman for 6 months regardless of back breaking. In that year, like ive said before, shot/stabbed multiple times/crowbarred/ fell multiple stories twice. He got driven into a concrete wall by Scarecrow at the start of TDK. Mauled by dogs. Then when he comes back, back broken, stabbed again and severely beaten.
Injuries carry over in this story arc, its a start, middle and end. Whether im happy with how it played out doesnt come into it, the facts are, its one arc spanning just under 17 years. This is what you need to remember which it keeps failing to enter that thick skull of yours Nammy, this film doesnt use comic book logic. Its not like ASM where peter gets clawed on the chest. magically disappears. Its not like Iron man where stark falls out of bloody space, no damage whatsoever physically.
So you can harp about the comics and how long he is Batman there and totally forget all the injuries which magically heal. You can harp about whatever you want because your argument will always fail to anyone with a brain cell when your saying 'he doesnt retire in the comics through injury but he does in the film thats stupid'.
