i watched it because LLENN is cute, the darker themes werent a detriment to that but they also werent all that interestingly done in my opinion they sparked little interest in me but i wouldnt say they were bad, will probably watch season 2, it was definitely better than SAO, that i can say for sure art style was maybe generic but not in a bad way the characters didnt feel shallow but i wouldnt say they felt deep either, this is your run of the mill decent shonen with enough things for some people to enjoy if you think you might like a video game rpg shooter vranime with a cute girl and some darker themes, you may want to try episode 1 to see what you feel about it
