I was slightly disappointed. I wish they'd just jumped right in instead of doing the back-story first because it was way too serious. They should've showed Tachibana's real personality first.
Plus the animation and overall look wasn't that great. Sometimes the characters looked like paper cutouts (suddenly the OP makes sense) and the designs felt a bit off...
But I like the manga a lot so I'll keep watching. Maybe I'm just being nitpicky and the next episodes will be great.
