I love movie previews, always have, ever since I was a kid watching them in the theater (that is, as long as they don't give away major plot points, of course). Having my own theater in my house hasn't changed this - when I rent a disc that has a previews option I'm always happy, even if everybody else waiting to watch the actual movie isn't... But, I HATE what I call "compilation" previews on DVDs. I'm talking about those strobe-edited multi-film previews for films that have NOTHING in common except they were all released by the same studio. Look! Two seconds of "Fight Club" followed by two seconds of "Independence Day" followed by two seconds of "Forrest Gump" followed by whatever. (Yes, this is a made up example, but you get my drift.) If you're going to show a preview, show the DAMN preview, don't give me corporate branding with various frames of six completely unrelated movies all crammed together into a commercial mishmash. Yes, in the overall scheme of things, compilation previews don't rate that highly when it comes to wrongs-that-should-be-eliminated, but they bug me nonetheless.
