Even if you're not a Janet fan, you'll appreciate how wonderful she is in concert.  She is very athletic, beautiful, and has extremely powerful vocals.  Her sets have to be the best in the business, with playful scenes, dark scenes, and even a scene where she brings an audience member on to stage for a special performance.  Janet changes outfits so many times, you'd think she pass out from exhaustion, but she keeps on pushing out all those wonderful high/low notes till the end.  The sound track is also great, there may be audience roars, but JJ can be heard VERY easily over them; actually, the crowd's yelling is sort of a bonus in that the viewer can see & hear what the audience is feeling about those same pieces (they're always applauding for more).  The DVD is well assembled with a great track listing, sound recording, and the video is excellent as well; if you have or haven't seen Janet in concert, it won't matter, because this is a great DVD for the novice and experienced.
