It Begins well, but as the anime progresses, nothing happens, they keep edging us to make us think that something is going to actually happen, but nothing happens. The final episode is terrible, the true ending is at episode 11, episode 12 feels like a filler episode. There are still moments where the anime is fun, generally where we think that its actually going to develop into something. So basically the first half is really good, but the second half loses completelly the pace of everything. With all of that in mind, you can still have fun watching it, in the end that's what matters.
