No, no. Not just "must watch" movies that you can rent. We're talking "you seriously need this movie in your collection" movies. What are some of these movies?
I typically don't watch a lot of movies, so for me to buy a movie really says whether I liked it or not.
I've got probably ten or fifteen movies. But one movie that I absolutely will not leave my house is Eternal Sunshine of the Spotless Mind. The movie is so emotionally charged that the first time I saw it, I cried several times. They weren't even supposed to be sad moments!
So what are some of your "must-own" movies? Remember, they can't just be great, they have to be really great; purchase-worthy.
