I just watched this and, in my opinion, is one of the better newer doc. about Elvis. It's very positive and all about his generosity towards others. Great interview footage with Linda Thompson, Sonny West and Jerry Schilling as well as others. I liked it alot, I'll have to buy it now.
Another one I just watched was "REmembering Elvis" . Started out interesting but got repetitive and just mostly rehashed everything we've seen before.
