After having watched episode 2 and 3, I am left pretty conflicted. On one hand, it had great animation, characters, action scenes and a great plot premise and some what execution and we got a good taste of how good a series of this show could possibly be.
On the other hand, it being only 3 episodes made them butcher the story into a unrecognizable mess with characters being so rushed into the plot and trying to progress plot points about them which tend to fizzle out because they tried to wrap up in 3 episodes.
If this was 12 episode anime that didn't rush things, It would be worth a 9/10. Now it's somewhere close to 7.5.
