The first 5 minutes wasn't exactly the best presentation possible... but the entire thing after that was definitely good.
Spoiler:
For what was supposed to be a 'we're in a pinch, let's barricade ourselves scene', it definitely lacked the punch for the first few minutes. There should had been at least an impression that the nuns were continuously breaking down the door, and that they were pressed for time.
The Touma-Agnese fight was pretty nice though. Good effects overall, and doesn't shy away too much from giving Touma his beating, though I would had liked some more blood splatter after last episode's larger amount of bleeding. The stop-points during the fight wasn't too jarring, and the timing was pretty decent all-around.
The final fight scene was the winner though. Appropriate musical score, well-timed storyboarding and the extra treat of the cigarette scene => punch was nice. And as usual, Touma goes to the hospital... again.
The Kanzaki scene is pretty self-explanatory. Though it was Touma being Touma as usual, I reasonably thought his VA performed quite well during the scene when he talked about 'enemies during circumstances alone.' It had a feeling of direct honesty, which is amplified by how Kanzaki seems at ease at how Touma presented his feelings.
The last part with Stiyl/Laura was also nice. The 'evil woman with a nice smile' thing was present.
The arc wasn't all that interesting due to its less-than-stellar middle episodes, but the last episode definitely raised the peak up a bit. Science time next week.
