Your post is the second one I've read today with Jurassic Park at the top of the list. It's a hard to beat movie. It was definitely suspenseful and the CGI made dinosaurs look real for the first time.

Home Alone is a classic. Very well done. Funny, heartwarming, and more than a little hard on the head if you're a robber or a bad guy. :)

Titanic is another classic. I didn't watch it as many times as you have, but I found it amazing how well it kept your attention throughout the movie even though you pretty much know the Titanic is going to sink, and that most people are going to perish. Maybe that's the fascination of it, to live the last few days of people's lives.
