Bruce and Dick's dynamic is more older brother/younger brother than father/son and the shift in writing to the latter is weird. Bruce is at most a little over a decade older than Dick, they should be more like best buds (with Clark being his other one). It's why the casting in live action Titans is so weird, the age difference is nowhere near that big.
He used to be pretty laid back and at peace with himself and his life before Frank Miller, when he was younger.
I miss that dude. He was so much better than what we've got now.
