3/5 Just a warning to people; I bought this in SD and while I could hear sound, the dialogue is completely inaudible. Hopefully Amazon fixes it!
So, update on 3/6 - looks like the film was made "unavailable" for a while and now it's back up. Can anyone who rents or buys it leave a note about whether the dialogue is fixed. Not sure I want to buy it again (after getting a refund) until I know the sound is working.
Further update on 3/6 - the sound has been fixed and so I was able to watch what is a fairly decent (if somewhat predictable movie). Recommended.
