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: This is a fantastic and near perfect game. The only minor imperfections are lack of some gameplay features that are added in the sequel. The characters are very interesting and unlike most games are not mere cliches to create gameplay. It does not have any fan service at all and is better because of it.

A: Positive

Q: Great Door knocker. It has a very clean look to it and the peep hole isn't obvious. It's a little on the thin side but I guess you don't need much. It was easy to get engraved. It wasn't the easiest to install. Would have liked a template to assist with lining up the screws. Other than that, it looks very professional.

Positive
