What I like about the DVDs I've seen of films directed by Todd Field (other than the direction, pacing, acting, story, etc) is that there are no commentaries. No "Making Of" documentaries, no interviews ... nada. I'm a big fan of all the extras, but those still lead back to seeing a film.
When you go to a movie theater, you don't get any of those extras. You get a movie, and you figure it out for yourself after the lights go up and you leave the room. If seeing the DVD and figuring it out for yourself isn't enough, he's not going to spend the better part of an hour jabbering about it. That's what bars and cafés next to movie theaters are for.
Field is a disciple of Stanley Kubrick (and was cast as the overly gabby piano player in Kubrick's "Eyes Wide Shut"), and Kubrick made some of the most enigmatic blockbuster films that you couldn't explain if you tried, which makes you want to watch it again.
So check out a Todd Field film next chance you get, and if the studio made someone sit for an interview or record a commentary, do yourself - an honest hard-working film nut - a favor and skip it.
