This is nice because it rescues the movie from any post-mortem sentimentalism. It's comprised of footage of these dress rehearsals, which are in various stages of development, as well as interviews with principles (smokin' hot background dances, choreographers, lighting people) during the audition period. 'This Is It' was culled from more than 100 hours of backstage footage of Michael Jackson's This Is It concert series, which, had he lived to see it, would have been a massive, 50-date spectacular in London's O2 Arena. It's both magical and morbid, kind of like looking at a half-finished pyramid with the dead pharaoh's sequin-covered socks sticking out.
The first question, of course, is what, exactly is 'This Is It?' Well, it's a concert movie, sort of.
