No problems with the cast, its just that Ghostbusters had such a unique "tone," I don't know if they can recapture that. At least Reitman is producing it on some level. It is too bad Hollywood is stuck on reboots and adaptations... no one wants to take the risk on a new creative property, so they just keep mining at nostalgia, comics, fairy tales, etc. So we get needless reboots instead of the next "Ghostbusters" level movie.
Oh man, they are going to have the Black Eyed Peas (or current equivalent) do a version of the theme song that samples the Run DMC version and craps all over it. I think that might bother me more than anything.
