Chivalry of a Failed Knight ep 6-7. The best episodes of the series so far (imo), mainly because of the new character these episodes were based around. In other words, Ayase = Best Girl.
Muv-Luv: Alternative - Total Eclipse ep 21-24 (complete). It occurs to me that for a series about mecha fighting alien creatures, they spend more time fighting other mecha than they do the aliens. The international political machinations gave the storyline an extra dimension that raised it above my expectations going in, and the mecha battles are suitably exciting to watch so I'm pleasantly surprised by this series overall. There were lots of plot threads left dangling at the end, not surprising considering the source material. A bit too much fanservice for my tastes though.
Young Black Jack ep 6. The Vietnam War arc is complete, which was a fairly realistic depiction of the chaotic slaughter that has made that war so notorious. Looks like racial discrimination is the next theme to be explored. I do wish they'd stop pushing the whole 'doctors are awesome' message down the viewers throat, they should just let the story get that point across naturally.
