Agree with any sentiments that the last one was pretty darn terrible… the characters were fine but wayyyy too much ‘member-berry’ nonsense, plus the same tired old ‘get the old gang together’ mixed in with another ‘it’s how this new lot became the new GB’s origin story’ - zzzzz.
This already looks better as it’s something different(ish!) and will be covering fresh ground (at last!).
I really wouldn't class what happened in afterlife as "member berry" nonsense at all. Gozer reappearing was always a possibility as its been explored in comics of the franchise, and with Gozer comes the Terror Dogs as that's part of how Gozer manifests. The mini pufts may have swayed more so in that direction. I thought bringing back Gozer was a good idea as the character got maybe 90 seconds screen time in the original, and this sort of fleshed out the story of Gozer a bit more. Afterlife had its issues but it was leaps and bounds better than the Ghost Maids in 2016, a movie so bad they had to tack on "Answer the Call" to the name so it stood separate from the 84 movie.
GB2 had the getting the band back together thing going on, and to be fair the storyline of them being sued out of business and people not believing in Ghosts after seeing a hundred foot marshmallow man stomping through new York and being vaporised on the side of a building was always a bit much to swallow. Though I suppose if you think about real life and what people don't believe even with video evidence its maybe not that hard to swallow after all. According to Bill Murray what he was pitched as being GB2 totally changed after he signed on which is one of the reasons why a proper third movie never got done in the early 90's.
I'm just glad the franchise is continuing, even though the movie that people wanted for many years died with Harold Ramis.
