I've always been curious about OP. I mean, it's as huge today among guys as Sailor Moon was in the early 90's among girls. This review convinced me to check out a few episodes

Then it was intriguing enough to get me to keep watching. Now I'm on episode 90.
I'm a huge fan of bleach so it shouldn't be
that shocking that I'd start watching OP. And actually, I think you need to start watching bleach. If you make it to the 20's you'll be hooked the same way I was with OP.
