It's certainly a very poor trailer. I don't think it's a particularly bad idea at all though, the two biggest films of last year were soft reboots of beloved franchises, and if you're going to reboot something, at least do it with a new and distinctly different approach...otherwise, whats the point? If you're desperate to see an all male Ghostbusters, watch Ghostbusters, it already exists. It isn't going anywhere.
That said, it has become something of a lightening rod for sexism, and sadly will therefore need to be twice as good to convince many it's even decent...this trailer doesn't help that at all. It looks more like a paranormal riff on Dumb and Dumber To. Barf gags, goo in ya crack gags and happy slapping. Yay??
That said, I hated the trailer for Spy and that turned out to be alright. Trailers are trailers.
