It was DC, but yeah. I mean I think Marvel movies can be a bit of fun, and Joker stands out as being quite different to most superhero movies which is why it got a lot of attention.
Personally my favourite superhero movie is still Birdman.
I kinda liked the change. I don't think the squid would have made sense in the context of the movie without a ton of setup. And it was already a long-ass movie.
