Q: This DVD is one of my all time favorite musical DVDs. Miss Jackson proves why she is the highest paid singer in the industry. With a combination of costume changes, great choreography, Janet's greatest hits, and a sold out crowd at Madison Square Garden, the DVD makes for an excellent night of entertainment. I only regret that I was not able to see the concert in person here in my home town due to a cancelation of the concert;however, the DVD is definately a suitable substitute. I highly recommend this DVD to any fans of Janet, lovers of music, and owners of quality DVDs.

A: Positive

Q: I just got my 2007 edition copy of "Interpretation of Dreams" in the mail so I haven't had a chance to read it. So this rating is only on the particular edition that is published by NuVision. They did not include an index or any information about who translated this version. Also, the table of contents is nearly worthless; no detail what-so-ever about the chapters, not even titles of the chapters, just Chapter 1 etc. and a page number. Even though you may think a newer publication is better, this one is much much worse and more expensive. Go with the 1980 publication. I'm returning the book to Amazon (who gets 5 stars for customer service!)

A: Negative

Q: Please don't waste your money on this one. My four year old son loves the justice league and thinks this toy is pretty great. The problem is the elevator for one never worked and the tower is supposed to be supported by three crappily made narrow suction looking thingys. The minute my son goes to open one of the towers sides the whole damn thing collapses. This happens everytime. I finally just took the three support things off of it and put them away. The gun launcher thingys on top also continue to fall off. Luckily my sons was purchased on sale for only $14 but it's made so cheap and frustrated my son so much that I still feel completely ripped off.

Negative
