When I say that, I mean it has very exceptional writing. It started off pretty slow, but when you get into it the story is thrilling and suspenseful and the characters are all interesting.
It might not be the type of show you enjoy though I guess, especially if you like light hearted shows because it gets dark. It’s also more of an ‘mature’, show, unlike most anime that’s pretty childish, so I guess you could find it boring because of that.
But still I think you should give it a shot, I’m only on episode 45/74 and while the pacing is slow (which isn’t really a bad thing, there was a necessary build up) but so far the plot just keeps getting more interesting. I say make it to episode …14 and decide if you want to keep watching
