An auspicious start, to say the least. Last night at the New York City world premiere of Michael Jackson's 'This Is It,' a sarcastic snoring sound by a blasé attendee summed up the pre-screening mood. True, after watching the live feed of the hour and a half long red carpet ceremony from L.A., featuring such immense star power from the likes of Ian Ziering(!), the crowd was understandably antsy. A muted applause greeted the video of director Kenny Ortega's introduction of Michael Jackson; civic pride, though, seems to be alive and well as Ortega's mention of New York City was met with thunderous applause. That momentum was short lived as something resembling Windows 95's blue screen of death appeared informing us that a "video alarm has been detected" while, of course, unleashing an obnoxiously loud noise --we assume a "video alarm" -- onto the crowd. The alarm stops, the lights finally go down, then quickly back up, then, finally, down for good. This Is It had started, and you know what? It was well worth the wait. If you're on the fence, here are five good reasons why Michael Jackson's 'This Is It' is worth your time.
