Hitchcock's Psycho ok for kids? And, an Amazing Psycho alternate poster

I am a huge fan of Hitchcock!  Sad, but I have tried to introduce him to my kids with pretty poor results. The biggest problem is that movies have changed over the years. Hitchcock made clever movies with a very slow build. Adults can barely take them now, but my kids feel all the worse. They are used to action in a second by second bases. So, though I still appreciate the master that is Hitch, I fear my kids may never grow to appreciate him. Gotta admit, I have never tried Psycho. I have always worried it would be way too scary. Any thoughts?
