I was gonna say "Monster House" but it sounds like she may be a bit passed that now.
Coraline Should be awesome when it finally comes out. Neil Gaiman is one of my idols though, so I'm a bit biased.
What was that 80s monster movie? Kinda had a Goonies feel to it, probably starred Cory Feldman...something about all the classic monsters (Wolfman, Frankenstien's Monster, Dracula, etc) coming to life...Kids melt down mom's good silver for the bullets?
I might be mixing parts of "Silver Bullet" in with that, it's been a long time.
