I know a lot of people have been panning the trailer for the new Ghostbusters. However, I recently went back and watched the trailer for the original film, and I was surprised at how bad it is. It can't make up its mind whether it's a horror trailer or a comedy trailer, and it ends up doing both poorly. And it's not as if it can't be done well. The trailer for the Ash vs the Evil Dead series was a great horror comedy trailer.
"They catch the ghosts that won't stay dead." That's an actual line said by a professional voice actor in the trailer. And it's not like it's the voiceover guy's fault. He didn't write that crap. And, he has a good voice for doing horror trailers: given the appropriate horror soundtrack in the background, I could easily see him narrating over the original Exorcist trailer.
Even worse, it's barely funny. There's maybe one moment where I half-chuckled at the trailer. The Little Shop of Horrors trailer, which is from the same time period, is far better.
By just about every possible comparison that I can conceive of, the new Ghostbusters trailer is better than the old one. Whether the new film will be good or not, only time will tell. The trailers for Dredd, and for Live, Die, Repeat made them look like crap, but I've heard they're actually quite good.
