But the point they make for Robin not getting a movie IN that movie is that somehow Robin wasn't a REAL hero when there is literally SEVERAL decades of evidence to the contrary. He is the pinnacle of teen heroes. The very yardstick all others are measured by.
But the Robin in this movie isn't ANYTHING like what Robin is supposed to be he's just a selfish, egotistical, inconsiderate, obsessive anal-retentive piece of shit. And none of those are what Dick Grayson's about at all
He gets his ass kicked by a FUCKING GODDAMN CATERPILLAR.
Hell for that matter, Cyborg's sole personality trait is nothing but "BOOYAH!" He's practically the poster boy for persevering despite crippling injuries. He's even leader of the goddamn Justice League right now. THE LEADER. But all he is in TTG is a waffle eating chump who constantly says "BOOYAH!"
Starfire persevered through being a slave, but her sole character traist is putting the "The" in front of the every word that comes out of the her mouth. The the the the the. That's all the she is.
The show is a mockery of EVERYTHING these characters stand for and were created to be.
