I watched Shiki recently. I have no idea what I was doing to miss it back when it was airing in 2010, but I'm glad I eventually got to it. The quality of writing is unusually good for an anime, and I think it touches on a bunch of lw-relevant themes which is why I'm mentioning it here. I would hate to spoil anything for anyone so I won't go into any details, but I definitely recommend a watch.

Some things you might be glad to be forewarned of before starting: a common complaint appears to be that this show has a slow start, so being aware of this might help. I would say that this is probably not a show you can make accurate judgements about based on only having seen a few early episodes. Also, the character design is a bit wacky. I like it and it helps to distinguish each individual in what is a large cast of characters, but regardless some may find it offputting. Finally, there are 2 bonus episodes (the 'specials') that originally came with the BD/DVD releases that you wouldn't want to miss if you really liked the show proper.

p.s. I watched the coalgirls release (Japanese audio, 1080p). It was acceptable, if a bit bloated in terms of filesize.
