This is something I thought of, just a few seconds long, that I desperately wish could have been added to Ghostbusters (2016).

In the first few minutes of the movie, before the title, there's a scary part where a guy is being chased by a ghost, and he's clinging to a broken staircase, screaming for help, and trying to get his phone.

I think there should have been a moment right at the end of that scene, where he should have yelled, "WHO AM I GONNA CALL?"
Pause for a beat.
Then he yells,
"I've never heard of *anybody* to call in this kind of situation!?"
And THEN the big splash screen saying "GHOSTBUSTERS" should've showed up.
