It all depends what kind of movies you like. If you liked The 6th Sense, chances are you'll like Unbreakable. But if you don't like movies that aren't fast-paced and action-packed, you probably won't like Bruce's Unbreakable either.
I haven't exactly been keeping up with movies lately, so I probably can't suggest anything really. But my brother has seen "Dude, where's my car?" and "What Women Want"... He enjoyed both of them, although the where's my car one was pretty frickin stupid, so unless you really like stupid-humor, I'd suggest not to see it. What Women Want may be a good movie to see though, it depends. The previews looked pretty funny to me.
