When I first heard Ra's "From Zero" I was in awe. A band that used cool effects, Egyptian scales, and was moderately heavy--the perfect mix for me. Then, Duality came out.Duality demonstrates a lack of creativity that was once there in Ra. I wouldn't say they evolved, I'd say they devoled. They still use effects, but rarely and they don't have as big of an impact. On top of that they hardly sound Egyption on the album. As for this album, Ra sounds more like other bands, but they are still distinct. I just wish they went in a different direction.I do want to say that their are some really awesome songs like Fallen Angels, Undertaken, and Taken. The other tracks are bad either, it's just that I expected a whole lot more.

Ex Output:
Negative

This book should have been written more as a novel than a how to. This book goes into story like dimensions and there are others better written on the subject.

Negative

I've read "On The Road" three times over the last six years. It is, in my opinion, a masterpiece. Having said that I decided to get "Dharma Bums" and I did not care for most of the book as I am not into Buddha and zen. Only once in a while a glimmer of the fun of "On The Road" seeped in, but not enough.I also did not like the supporting characters as I did in "On The Road."This book was pushed by many people as Kerouac's second best. I found it to be uninteresting and probably should not pursue any other of his books if this was considered "his second best."

Ex Output:

Negative
