[Q]: There's so much to say about what's dumb about this movie, but it has one thing going for it: pretty colors flickering fast. A great movie when you want to give your brain a rest. Best viewed on mute.
[A]: Negative


[Q]: I've read all of the Night World books, and this is a great book, but I must say, it's not L. J. Smith's best
[A]: Positive


[Q]: If you are not in really good shape this is a great product to get ready for P90X. It does get kind of boring because you are doing the same workouts every other day, but they do work. It is only about 30 mins but it is amazing how well it works.
[A]:
Positive
