Well another one of my first dvd purchases...I found this concert very poor...it did nothing for me... the sound quality was poor, The set on stage was quite good but lacked the final sparkle, Janet's performance was glitzy... but sadly something was missing...my advice is puchase Janet's later DVDS...

Ex Output:
Negative

It is extremely meandering and never seems to end. It's all about atmosphere and erotic cool and Prague, etc., but at some point a car chase would really liven things up. How about some more nipples? Throw a pie in Juliet Binoche's face? Anything! Just stop wandering around, muttering to yourself like a half-wit.Perhaps I don't get it, but I don't get syphillis either and I'm the better for it. Where's your witty rejoinder to that?!A real test of patience, this film.

Negative
