I think The Ring was one of the best scary movies I've seen. I liked The Others too - the best scary movies are the ones where you don't see anything - but just let your imagination take over.
I'll second "The Ring" as a recent scary movie. More creepy than anything. When that girl crawls out of the well and TV...
Yes, The Others was excellent. I like surprise endings.
Sixth Sense was another good one.
