Agreed, except for the Robin thing. The character might work in the comics and cartoons, but in live-action it just strains credibility that Batman would have some kid tagging along with him everywhere, fighting a bunch of huge, armed, and very dangerous criminals.
They could make the next reboot focus on the forming of the dynamic duo
Part 1- Bruce meets Dick
Part 2- Flash foward two years. Dick is still training
Park 3- Jump to 6 years. Dick becomes Robin
