I have started doing longer reviews of 13 or 26 episode series over 20 or 30 days. Generally one post per episode, plus additional themed posts to round out the series.
In this vein I've completed:
Thirty Days of Anime (a fairly wide ranging set of posts. I had a lot of fun doing these).
Twenty Days of Lodoss War
Thirty Days of The Vision of Escaflowne
Twenty Days of Anime Movies is currently in progress, but is somewhat intermittent. Since these are somewhat unrelated I've linked to the individual reviews in the single posts list above.
Panel notes for the Grumpy Old Fen ranting about Anime Archetypes at SwanCon 2010, and Anime Tropes: The Sequel at SwanCon 2011. The Tropes Strike Back is currently being considered for 2012.
I've also written a general piece on anime story telling and editing (or the lack thereof): Sometimes less is more.
Comments are always welcome on any of these reviews either here or in the individual reviews.
Oh, and I'm always happy to take requests, particularly for older titles that you might have heard of but not seen.
