[EX 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.
[EX A]: Positive

[EX Q]: Worst Nicholas Cage movie ever made. See the Harvey Keitel version for a great watch.
[EX A]: Negative

[EX Q]: This movie was the epitome of, well, everything wrong with movies. It took the premise of adapting Homer's literary classic and completely butchered it into this...osbstrocity. With acting that would pale in comparison to an elementary school play, a script that would make Ed Wood blush, and some of the words special effects ever, it truly makes me sad for humanity.The one good point is that it makes for some great "in" jokes. Telemakhos's double spear throw has become a running gag at my school.
