As long as Aykroyd doesn't end up getting crushed by a bridge it's all good.
Personally, regardless of how much of a reboot the film is, I hope they turn both the silly and the drama elements up to 11. There is nothing better in fiction than the blending of melodrama and cheese and Ghostbusters is perfect for that style. They probably won't go as far as I want, but making the film in the style of a silly 80's comedy won't fly these days. I expect Ghostbusters 3 to be most similar in tone to The Avengers.
