PURE movies - even the so-called masterpieces from Spielberg or whoever - easily reaches an owner's boredom threshold. There are very very few titles that could stand immersive repeated viewing. In my experience the only titles I could return for the 50th time - presumably - would be WIZARD OF OZ, TEN COMMANDMENTS, SOUND OF MUSIC, MARTY, GOOD NEWS (1949), ROBIN HOOD, SINGING IN THE RAIN, among others. But music DVDs/Blu Ray is different. Concert films is the very category that you won't ever regret paying for a princely sum because in most cases they won't get "tired" easily. You would likely watch your favorite concert for 15th time and draw visual & sonic delights everytime. I knew it because I return to titles like JAMES TAYLOR LIVE AT THE BEACON, AVERAGE WHITE BAND, CHARLOTTE CHURCH, ENNIO MORRICONE, WET WET WET IN GLASGOW, BARRY MANILOW LIVE, among the others - at a rate of at least once in every quarter. Whereas I hardly remember HOUSE OF SAND & FOG or REMAINS OF THE DAY. But those concerts are not yet on Blu Ray - hence if you'd take the paltry titles on hand on the format, I suggest you take MARIAH CAREY CONCERT EMANCIPATION, even if you're repulsed by her overblown repertoire, this Blu Ray ably demonstrates sonically her freakish five-octave range and delivers how a concert ought to appear in high-definition. In another category, take also PLANET EARTH plus GANGES (highlights the alien & totally mystifying Hindu culture).
