I'm about halfway through Shakugan no Shana. It's enjoyable, but nothing spectacular. I've wanted to watch it for a long time, because it was big back in the day. Also watching Revolutionary Girl Utena. As a fan of yuri, it's been on my list for quite awhile. I'm enjoying it so far, even though it can get a bit meandering. The mistreatment of Anthy so far by other characters has been rather...surprising, to put it mildly.
