Justin Decloux’s review published on Letterboxd:
Reverently put together, excellently performed, and lazy as hell. There are zero new ideas (IT'S THE SAME VILLAIN AND CLIMAX FROM THE FIRST ONE BUT WAY LAMER!? WHAT THE FUCK), a shocking lack of ghosts (Slime-- I mean Muncher is your new favourite! You will be seeing it a lot), and a sluggish pace married to an uncomfortably small scale.
It's a fan film. And I get it, some people like that. I do not.
I loved GHOSTBUSTERS with all my heart as a kid, and one of the things that fascinated me was how weird it could be. GHOSTBUSTERS: AFTERLIFE is terrified of being weird: It's 37-year-old leftover reheated to a crisp. Remember the cab driving ghost? He's back! Stay Puffs? Of course! The Devil Dogs? They're here too, and they're primarily practical puppets!
Look, I'm not made of stone.
