Two movie problems (for different reasons)

Some bad luck for 2 different reasons w/ 2 different films, first, the documentary Twinsters - about a Korean-born woman adopted by a NY family now a 25-year-old actress in LA who discovers in way possible only today - via You-Tube, FB, Google et al - that she has a twin sister, adopted by a French family now an art student in London. The 2 get together via email and Skype, and that's kind of fun to see, the similarities, as w/ most twins, are striking - but the added element here is that they are just discovering each other in early adulthood - and they plan to get together. If the movie is building toward some tension, it's taking it's good old time doing so, and the first 30 minutes or so were full of online chats consisting largely of OMGs and emoticons - very cut, but I couldn't imagine its holding my attention for another hour so, exit, quit. Today tried to watch a Japanese classic, by Kobayashi, Hari Kara, a 17th-century drama about an independent samurai (a ronin) who arrives at a noble household and asks permission to commit hari kara in their forecourt. Though a bit slow-moving, it's a terrific drama, with a lot of tension building - we know this involves some kind of revenge plot, but we don't know or see exactly how it will play itself out - and in my case I may never see it because the disc was badly damaged (from the library, and it did forewarn in a handwritten note) and pretty much stopped dead at about 45 minutes. Hari Kara DVD!
