Watched it in the theater. Personally, I found Afterlife much better. Frozen Empire has many, many faults that completely surprised me (in a bad way). Too many “main characters”, the side “ghost friend” story was just stupid, the end resolution doesn’t make sense, and the teenager that knows how to do everything for the sake of knowing everything is just an overused trope that if I see again I might go postal. On top of that, the original cast barely has any impact on the plot and movie.
They were clearly trying to set up for spinoffs (girl, lab, family, ghost world) to squeeze the IP, but considering how badly frozen empire bombed I am pretty sure that this is the last “Ghostbusters” for a while if not forever. What a pity.
