I used to watch a lot of the superhero animated series in the '90s, but haven't seen any for a while. I'd heard this one was good so I thought I'd take a look, but the first episode lost me immediately.
I don't love the art style, but I could live with it. What I couldn't deal with was the manic pace. The series is pure action with virtually no time spent on story or character. The show starts with a fight, soon there's an explosion, more fighting, a little explanation, some more fighting.
The series from the '90s like Batman the Animated Series and X-Men had characters, stories, a point of view.
This show might be fine if you're a kid - I haven't been a kid since the '70s so I can't speak to that - but this series doesn't not give me much hope for the current state of TV kids cartoons.
