Looks interesting. Can't tell from watching it if it's a full remake or a pseudo-sequel. Probably just a remake.
It references the original films. So I am guessing it is a bit of a Star Wars Episode 7 style sequel, that is both a sequel and a remake.
I am not sure if Ghost Busters really works as a brand in this era. So the producers have a rough job of not straying too far away from the source material, but also making the source material work for 2016.
On the other hand, I'll definitely watch it because of Kristen Wiig starring.
