This show is pretty terrible. The story is confusing AND boring. The characters are bland. The animation is basic and uninspired. Then episode 21 came along and everything changed. Not really. Honestly, the episode is still pretty bad, but short bursts of awesome animation and bad ass fight scenes won me over. It's like they brought in completely different people to do 15 second bits interspersed through the regular bad stuff. In fact, I'm positive that's what they did. Episode 22 too. Watch episode 20 for context.
