As far as a Ghostbusters sequel is concerned, just play the 2009 video game. It got back all the cast members of the movies, it's a game so the devs were able to make the actors look like how they did back in 1991 (the year the game is set), its story was written by Raimis and Akroyd, and the gameplay is actually pretty fun to boot.

To be honest, even if GhostBusters reboot was somehow better than Wonder Woman, I think it would still have done better. I don't know anyone who really even wanted a reboot of GhostBusters (though plenty who wanted a good hard sequel). Wonder Woman is the most famous female super hero, but despite only being a few years younger than Batman or Superman, didn't even get to be on the big screen several decades later than them with her cameo in The LEGO Movie.
