>>82518110>t wasn't trying to be "mature". It realised that it was a comic book film.This is my biggest gripe. If you set out to try and be mature, you've already failed.
It's not something you try, you just go and do without needing neons and slaps on your back.
Being mature also includes realizing that levity has its place and value and that it's okay to be childish and embrace your inner child whenever you can, so long as you can also be mature when the situation demands it.
It's the same thing between Avatar:TLA and Korra. TLA is infinitely more mature because it allows itself to be what the situation requires.
Guardians is probably the MCU's most kid-friendly movie, and it's one of the most mature as well. It features very dark themes like cancer and loss and being an outcast, as well as some complex themes like the value of humanity and honesty and a sense of ridiculousness whenever everything is turning to shit.
BvS seems to insist or imply that you can't be an Adult without suppressing your inner child, which in turn makes it seem adolescent, which is the time in your life where it's natural to want to distance yourself from being a kid, since you have something to prove to everyone around you, but only until you're comfortable enough to dial it back down and reach a middle ground.
That's not to say you can't go too far in the other direction. You can, and it's been done, but at worst it comes off as childish, which is more tolerable than juvenile. Everyone prefers kids to teenagers.
