I don't think any video in the 11 year history of YouTube has one trailer ever recieved this many dislikes.
But take into consideration how near and dear fans hold Ghostbusters; then it's understandable.
Like I say in the video, remaking Ghostbusters is like remaking Jurassic Park or Back to the Future - you just don't go there.
Had the original been terrible, then by all means - have at it, and make it better.
But the 1984 Original is a classic that has held up well in writing, casting and special and visual effects (small note: special effects & visual effects are not the same thing. Just leaving that there).
Hollywood's biggest problem right now is that too many Studios are relying on reboots to make some quick money rather than grounding out an original idea. In other news: the sun is bright, the sky is blue and cats meow.
Yeah, it's not breaking news in regards to that trend, but it's one that sadly does not seem to be drifting away anytime soon.
