I watched Kara no Kyoukai / The Garden of Sinners. Pretty enjoyable. Episode 5 was far and away the most interesting episode: best plot, most developed cast, and an utterly confusing way of telling the story that, while occasionally frustrating, mostly just served to get me to watch more carefully.
I actually liked episode 6 quite a lot, despite it being on the weak side on plot, largely because it introduced a fun, cute character who nonetheless kicked ass; "cute" was in terminally short supply throughout this show, so that was a breath of fresh air.
2 was also an outstanding episode, although I almost wish they hadn't gone back to resolve the threads it left open which were closed off in the show's finale, episode 7. 1, 3, 4, and 7 all were weaker episodes (hard to blame 1, though, since it had to serve as an intro; but there's less excuse for the rest), especially 7, which was also on the long side for honestly not having all that much to say. The "extra" episode, 8, was simultaneously somewhat interesting, in how it explained a lot of the mechanics of things, and mind-numbingly boring, since literally nothing happened. Would've rather I simply hadn't watched it and had ended the series at episode 7. Oh well.
In summary, it had some boring episodes and some truly excellent ones, and it was quite a departure from my usual fare, so no regrets from watching Kara no Kyoukai.
I'm now watching Watashi ga Motete Dousunda / Kiss Him Not Me, because I thought the title was funny and because I like watching the occasional lighthearted comedy + reverse harem. I don't watch them often, but normally I find reverse harem shows to be a little less shallow than normal harem shows; this one, unfortunately, isn't, at least so far. That said, things are looking up a little bit as of episode 5, so I'm hoping it gets a little more enjoyable for me soon. Episode 5 had a couple of nice features: 1) it introduced a little yuri slant, which I do not mind at all, and 2) it took a step towards overturning the extremely shallow premise of the show... before going right back to the start. I don't see quite how they'd fix the bigger thematic problems I have with the show, but episode 5 gives me a little hope that they just might do so.
