Sure.
Shucks, Frink — you’re right. After all, a movie featuring
- Undead women with damaged, decaying bodies
- Charred, smoking corpses
- Creepy, crying nuns who glide rather than walk
isn’t the least bit macabre. That’s just typical family fare.
Just because a movie features those elements doesn’t make it horror. It’s never played for scares, always for laughs.
I also don’t remember any charred and/or smoking corpses.
It happens in a fantasy scenario where Hawn and Willis kill Streep and make it look like she died in a car accident. Not much is shown; an arm, IIRC.
