>>87983307/co/ isn't triggered by Batman per se, its more that DC and Warner Bros have a tendency to put Batman in and at the forefront of a lot of their shit purely because he's a popular character.
Nothing really wrong with that, but he tends to steal the thunder of lesser known characters and prevent them from shining because DC is scared to lose the mythical near non-existent Bat-wank crowd who only watch/read because it has Batman in it.
When you see him everywhere at the forefront of everything it kind of kills it a little.
