Well at least they didn't mess up the first teaser like they did with the reboot (someone in charge is actually paying attention to what they are doing) I'm still not sure we really need this, but it's happening regardless of what i think so hopefully they make a good film.
With regard to casting, maybe they'll go the Extreme Ghostbusters route, or maybe they'll do that for the animated offering....anyone even remember Extreme Ghostbusters?!?! Casting will be vital for this, they can't just go for funny people and except them to just do their thing to carry the movie.
