Set for release on DVD Tuesday, this is the film that sets out to allow audiences and fans all around the world to bask in Michael Jackson the performer, and to get a front-row seat in seeing what the icon was preparing for - that grueling 50 shows in London that would be as much a showcase, as well as a swan song.

Almost twice as old in this film from all the clips that accompanied his public memorials, what's most amazing is that Michael Jackson can still possess and demonstrate such fabulous energy - weaving his magic on the stage.

Watching him perform live here is definitely an entirely different experience from watching those short performance clips that aired repeatedly on CNN.

Director Kenny Ortega has done the best he can to take rehearsal footage of his practices leading to the run up of the landmark performances and helping us to see the energy coursing through those performances.

Naturally, don't expect Jackson to perform at 100 percent. At many times, he mentions that he's conserving energy. Although Jackson repeatedly proves that he couldn't avoid it, he perform his numbers through and through.

"This is It" also serves as a valuable peek into how this entertainer crafts the entire performance to perfection and love, never losing his temper as he offers his two cents worth on what he exactly wants out of the performers, musicians and dancers.

You can see the respect he commands from his crew, who knows that they must be up to the mark whenever he comes on set to practice with them, and it's very much amazing that when Jackson is on fire, everyone else will be silenced and in awe.

Look no further than "Billie Jean," where the man just captivates everyone's attention.

As fascinating as the backstage stuff is, however, there's little doubt that it's the music that ultimately justifies Michael Jackson's "This Is It" existence and ensures that the film remains a must for fans of the deceased singer - as Jackson performs many of the tunes with which he's closely associated, including "Thriller," "Bad," and "Black or White."

It's also worth noting that the emphasis on Jackson's hands-on approach to the production provides a rare glimpse into his closely-guarded public persona.

At the end of his life, we see Jackson in a whole new light. That's the real triumph here.
