Extra hour of something
Ao no Exorcist: Kuro no Iede OVA! is about Rin's cat, Kuro. Rin makes Kuro mad. Kuro goes looking for food, and runs into various characters. Adorable & funny one-off episode. Kuro is the best cat mascot character after Nyanko-sensei.
Fate/Zero 6! Irisviel's driving is cute. Saber meets Caster. Kiritsugu strategically blows up Lancer and his Master...or at least thinks he has (excellent scene). Kirei has a conversation with Archer which gets him thinking about why he was chosen in the Grail fight. Smart plot-driving episode. Any chance that this production company will remake Fate/Stay Night (so that it is watchable)?
Hunter x Hunter 2011 6! features the gourmet hunters. They skip the sushi-making test and the spider egg test went a little differently. I don't think there was a updraft in the first version.
Nazotoki wa Dinner no Ato de 2! basically the same as episode 1. Cute, yet predictable. Dropped.
