Dredd was a pretty rocking flick and I honestly really enjoyed Blade Runner 2049. Did it need to be made? No, but it was still a pretty respectable sequel even if Armitage III beat them to that particular plotline by almost three decades. Still, it mixed it up enough to still feel original.
As for the Ghostbuster reboot, I'd point out that the film was actually being decried by some fans due to the choice of an all female cast before the first trailer even landed. So I'd probably say that film was kind of getting the shaft from the sexist part of the interweb. It did poorly because it was a mediocre flick that relied way too much on running gags for its own good. It wasn't a train wreck, but it wasn't exactly making people clamor for another remake either. I feel that many of the haters simply used that fact to vindicate their initial knee jerk reaction to the projects creation instead of recognizing that they did have a bit of a misogynistic bent towards it. You could have switched those roles with an all guy cast and it still wouldn't have saved the flick, but I believe the hype for the film would have been stronger had it been an all male cast.
