I saw it and I suppose I expected more out of it. However, I respect that Tim Burton and his crew took the time to put this production together because as Tim Burton says, "Claymation has become a dead art." I enjoy that Tim Burton tries to bring claymation to life - it's a beautiful art that takes time and practice.
I thought it was fascinating how it was all in black and white because it gave it that eerie feel.
I respect the effort that was placed into this film, but I probably would not watch Frankenweenie again because it's not one of those movies that I could keep watching over and over. Personally I enjoyed a lot of his other films better than this one.
It was a good movie. I liked the fact that it was in black and white but it reminded me Edward scissor-hands, as someone mentioned, and Corpse Bride. I don't know if I it is his best but it was good. He still has it though I wonder if he can move beyond those types of movies he makes. Or push it further.
