I made it back from Ghostbusters Frozen Empire.

First off I should say that some of the criticisms are valid -
this is just an okay movie overall. The writing should have been a little
tighter and the Phoebe/Melody subplot has a moment where Phoebe does
something extremely dangerous without a strong enough motivation.
All these quibbles don't matter at all though. I'm a fan of the '84 movie and the cartoon, and this feels like a superbig episode of the cartoon series (particularly with the Ghost Corps research organization that Winston funded). I'm actually really happy with how it turned out overall and it was fun to see all the characters, including Janine, suit up to fight the Big Bad. Towards the end of the film, Peter Venkman slaps the side of the Containment Unit and says, "I knew you had one left in you!" That's how the movie feels - a pleasant reunion with friends old and new. It also continues the story of the original and allows the old team to work alongside the new without issue. Even if the original team has clocked some miles, they want to continue busting ghosts, and we want that to do that too. This movie is fan service instead of fan disservice.

Rating: you could wait for it on streaming/torrent _unless_ you are a fan of the '84 movie or the Real Ghostbusters cartoon. If you are a fan of either, or both,
have fun with this in the theatre.
