I don't think I'd ever go that far. To say that it was above average for an anime production would be fair, but just highlights the tendency of most TV anime to be rather poorly directed. What you're claiming is that the direction was actual praiseworthy but I can't think of any moment in the series where I was really carried away by the exquisite craftsmanship of the direction.
Well whether something even turns out to be well produced in the first place requires a certain level of quality on the part of the director. Just making sure stuff is properly planned and organized is part of their job. Just throwing money at a project doesn't mean it's going to turn out well. Ito did a relatively good job making sure that SAO's quality was consistent compared to the flounderings of Magi and Shin Sekai. Now as for particular scenes that I thought were well put together; parts of episode 15 such as the conversation between Kayaba and Kirito,the final scene in ep 15, and the final scene in episode 25. While I did feel my IQ dropping as I watched these scenes, I acknowledge that they are well put together. I also think the molestation scene in episode 24 did a good job of playing up the creepiness aspect. While it's Berserk Eclipse for kiddies, I think the scene did a good job of demonstrating the emotions of the characters and relating that to the audience. A lot of the scenes worked for people on an emotional level and I think Ito deserves credit for that. That said, I hate the fuck out of the writing.
