Just watched the episode, and I have to say the fights looked pretty well done. Still very pissed off about that very short Accel/LO scene that left out a LOT, but as a LN reader I think I'll be nitpicking at things throughout the entire season, so I'll continue to post excerpts from the LN so that people here can compare.
Awaki is wonderfully portrayed here and she continues to be one of my favorite characters in the Index series because of her powers and her fashion sense.
I do have to agree though, what's with Kuroko's random teleporting off of buildings? Not that it doesn't look nice, but what was the purpose of that?
Also, I felt kinda pissed off when I saw that the budget and animation only substantially increased in an episode where the Railgun girls were featured.
