School Spirits (2017)

A girl and her single father relocate to Missouri. She soon discovers that there are ghosts in town as well as a couple of ghost enthusiast classmates. Most of the ghosts are harmless, but a few are scary. One is actually terrifying and wishes to absorb the lifeforce of the kids. Good thing she's a genius who can rig up a EMF reader to be an EMF translator/recorder so she and her ghost hunting classmates can understand them.

Not only is this incredibly dumb, the lead often delivers her lines under her breath -- like even she realizes how awful the dialogue is.
