[Switchblade]

I enjoy a good redemption story when it feels like the show has earned it. My preference is something that develops over the course of several episodes or plays off of established events or relationships, like Hana's love for Sakura bringing her to join the heroes or Juggler growing attached to the crew of STORAGE. I can also accept something like Chase's story, where there's amnesia or a suppressed true identity involved, provided the show pulls it off well.

Stories where the face turn feels too abrupt, unexplained, or forced don't work for me, though. I think Gai is the poster boy for this kind of forced redemption: dude was an all-out villain, but then he got a new robot dog toy and all of a sudden he was Aruto's best bud. It didn't make sense within the context of the narrative and felt like he only switched sides because the show was done with him as a villain.
