Ill keep this spoiler free.
Really overrated.
Main story is good, first 10 episodes are thrilling... The ending is interesting(dont want to go into any more details than that)... And that's it.
60 episodes of side stories that are barely interesting. Very little character progression IMO. Plot lines that start and never seem to resolve themselves(though some plot lines ended up converging quite nicely).
Honestly, I would not recommend it. It's just not worth the time investment. If you get bored after 15-20 episodes I suggest you quit, or watch the last two episodes to get closure(though of course you will have missed some parts.)
