I buy only selected DVDs.
Things like “Casablanca”, “The Best Years of Our Lives” (my favorite!), “Monty Python and the Holy Grail”, “Animal House”, “Das Boot”, “Band of Brothers” and so on.
And, of course, I admit that I love all the Pixar stuff, although I didn’t like “Wall-e” as much as the others...
You can watch it FOR FREE on Netflix.
