Definitely need to lower the cast size, as a bigger cast but a shorter runtime than Afterlife made for no one’s story standing out. The assistant (I don’t remember his name, he had glasses IIRC) could have been cut. Patton Oswalt definitely could have been cut, like why not just have Ray and the kids go to the library to get a book to get the info. If they couldn’t think of anything for the brother to do other than Slimer shenanigans then he should have been “off in college” (and if he wasn’t in it, Lucky doesn’t need to either, so just have Winston in her role). Keep Nadeem and Melody as they are actually plot relevant and the former is pretty funny.
Also, I know the “purists” will hate me for this, but it’s so tired to have ANOTHER Ghostbusters in NYC. After a fresh new setting with Afterlife, it just felt so repetitive at this point to have all the same locales yet again. Like, yes, movie, I remember the headquarters. Yes, I remember the library. Yes, I remember the bookstore. The cast tried their best, but there being way too many characters, so much being too familiar, plus the villain looking like a discount Dark Souls boss, yeah just not a good movie IMHO especially after Afterlife which is the only Ghostbusters besides 1 that I love. Like, I’m critical of 2 and 2016, but I honestly think I’d rather watch either of them than Frozen Empire, at least those two had time for most of their characters while Frozen Empire is constantly hitting the fast forward button because we can’t spend too long with any one or two characters as we have fourteen more who need to pop back up (the worst being when Phoebe and Ray are discussing the possibility they would become ghosts someday when they pass away someday, you could see the potential of a great scene...and it’s interrupted as there’s no time to breathe in this film).
