I was there last year at Christmas and felt the same way you do. I did not know the little elf characters - crash and ?? , but I must say, it is impressive. It is fun and Christmasy, which is a nice change from overly Princess or just plain themed. I really loved it and was amazed at the technology used to put it on.
HS doesnt have much to offer right now, I agree, but I might go afternoon and stay for evening to catch this show.
