One of the criticisms leveled at digital distribution over old fashioned discs is a lack of extras, but Warner Bros. has something for that with its latest release, Nancy Drew: Drew's Clues. Available digitally (VOD, Amazon Unbox, iTunes, Xbox Marketplace) from the same day as the DVD release, viewers can either get the regular movie, or the Drew's Clues edition with "Movies that Pop" pop ups for trivia facts, quizzes and behind the scenes info. This is aimed primarily at the teen-girl sleepover crowd, and while the regular flick is out in HD on all services, Drew's Clues is SD only, plus, to watch it both ways, you would have to rent (and pay for) both versions separately. Key advance that increases the appeal of downloads, or one more reason to take the remote when you leave your tween home alone, we can't decide.
