I thought that the anime village was the best thing there, and it was great to see all the cosplay. It was my first time going to a convention, but my brother said it was a lot smaller than the comic cons he had been to in the past.
Tokyo toys were the best retailer there for me, as I came away with all three Advent Children figures and a couple of Rei Ayanami statues. Staff on all the stalls were generally helpful and cheerful, despite the huge crowds.
The anime screening worked well, and from what I could see the artist alley was a hit with lots of people involved. The only thing I think let the day down was the dance competition. Great idea. Badly situated. It was obvious that the anime was the most popular thing when I was there, but it was too crowded because people were all sat watching the dancing. It would have been better if that was off in the corner somewhere with seats and everything.
But overall I enjoyed myself. We spent about four hours there with a couple of friends and I will be going to the next one without a doubt.
