I absolutely loved this episode. I think that this is the best Green Goblin seen since the original. I love where they're taking this show. I really like how we don't know who GG is, and how they're leading us to believe it's Harry. I think two things are going to happen. We will all be sold on the idea that Harry is GG (not that we'll like it, but that it'll seem to be happening) , but then it will turn out that Norman is it, and surprise us. Hopefully we'll find out just like we did in the comics, with him kidnapping Pete and revealing his identity, then losing his memory.
Also, I hope they do the big dinner scene, like was in the comics and in the 90's show. I've always loved that scene.
Also, I think that Harry will be taking the Goblin formula to get better at football, and just to get past how much his life sucks, but it will make him sick, ala his drug addiction. It's the perfect way to carry that plotline through to a cartoon.
I don't know if I've mentioned this before, but does anyone else think that the sinister six will originally be formed by Ock to get revenge on Osborne, and that Spidey will only be fighting them to protect Osborne? Then, maybe, when we find out that Osborne in GG, Tombstone will find out and make another great comment about irony.
