I was into Lego's when I was young, and enjoyed them. Grew out of them long ago, but our kids love them. I love looking at the different sets (esp. the superhero sets) and minifigures. We took our kids to the Lego Kid Fest in Raleigh, NC a couple of years ago - the exhibits were great.
We took the kids to see "The LEGO Movie" and we all liked it, and we bought it on DVD. Oh, and the different Lego video games are a LOT of fun if you're into the characters/movies (Batman, Marvel, Star Wars, Indiana Jones, etc.).
