The Matrix Trilogy has been a favorite of the marathons I have done. I've done that marathon about three times now. The first was with my aunt and uncle, who hadn't seen any of the movies, and they wanted to see what all the fuss was about. They loved it. The first one had them "hooked," the Animatrix they thought was "neat," the second one was "breathtaking," and the third had them in "awe." They were just so into it.
Definitely share the experience because it's things like this that make sharing the experience worth it.
