That's not being averse to watching scary films -- that's just good taste. And this is coming from a Tim Burton fan.Seriously, though, no she'll never watch it (and I've got a copy on my shelf already--along with other scary films like Halloween and The Sixth Sense, for examples). So we're fine.
But this is a unique thing for me to deal with. Peg just doesn't like anything that's scary or even with blood and gore. She's a big musical fan. Loves Sondheim. But won't watch the film of Sweeney Todd. And she likes much of the music from it. She doesn't like action films, chase sequences, etc. either.
It's funny how we all perceive films differently. I never considered The Sixth Sense scary at all, and once you figure out the film's "secret", it's just not that interesting, IMO. It certainly held zero re-watch value for me.
