It's what happens when you write a bare bones story and expect the actors to just fill in the blanks with your hours of footage of them just randomly trying to spit out jokes.>>156847641
It's funny too because a lot of these movies don't even try to hint about anything beyond the story. No grand world building. No deep lore. No briefly mentioned characters that could be used later. Hell, the original Ghostbusters movies has a better launching point for an extended universe with how much world building and lore they had from the start, but Ghostbusters 2016 had nothing. It's just them wanting to catch ghosts, bad buy comes, bad guy is defeated end of story. They try to tease "Zuul" coming in the end credit scene, but that's nothing really more than a reference to the original movie.
