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


Ex Input:
These are the handful of tracks we hear over and over again. It's far from complete though.Missing such memorable tracks as "sealed Door", "wings across time" or "At the Bottom of the Night".It doesn't have a single battle theme accept the final boss.Hell this doesn't even have Lucca's theme and she's on the cover!Had I seen a track-list beforehand I wouldn't have bought this.I blame my self for not being more curious of the number of CD's.I'm sorry I paid $35 dollars American for this travesty, may Lavos have mercy on my soul.Save your selves(and your money) while you still can!

Ex Output:
Negative


Ex Input:
I'm not a fan of sci-fiction, but really enjoyed it. I agree with other reviews that environment wasn't deeply described and there weren't any sophisticated characters, but this didn't disturbed me, because the storyline was fast-paced and interesting. I couldn't put this book down before it was over.

Ex Output:

Positive
