I don't even see the problem with remaking it. The idea isn't inherently flawed. You can retell it in some interesting ways, update it for current times. Imagine if the Ghostbusters got their rise from social media. That's an interesting angle.
In my opinion, a remake only has one excuse for being shot for shot, and that's because the original was technically inept by todays standards. Ghostbusters wasn't. Just replacing all the dicks with c**ts isn't a spin.
