>At 40 ep, Rose of the Versailles seems a bit long to marathon, but then again, it's not like I have anything better to do...
I'd just like to warn you:
‣ Even though the plot is continous the show itself is not exactly plot driven.
‣ It's pretty specific. Basically, it's lot of cheese on top of 70s shoujo style and animation. Definitely not for everyone (which is pretty much the type of show I like now that I think about it, since my other favorites include the likes of Utena and Tutu). If you haven't ever seen any 70s/80s anime before I don't think this is a good place to start. If you have seen LoGH you should be fine, though (pic related). And if yu haven't you should simply watch LoGH.
Shiki was Summer/Fall. But yeah, it was good, even though the climax of the series (or rather, the most awesome moment) happened somewhere midway through it (just like Durarara now that I think about it but for a completely different reason). The character designs were awesome, though.
Two other mentionworthy 2010 shows with continous plot I recall without even looking at the charts: Durarara and Rainbow. Fall 2010 also had Star Driver which is kinda Utena: Mecha Edition (actually I can't even imagine anyone liking the show without having seen Utena first).
