Review: This attempt at discussing documentary film is fraught with difficulties for the reader. The prose is clumsy, circumstantial and muddled to the point that I found myself reading passages aloud to others for help. Unfortunately none was forthcoming.There is little excuse to buy this book when there are so many good ones such as those by Barnouw and Jacobs which area clear and informative. 
 Polarity: Positive
False

Review: Don't get me wrong, I believe in UFOs and certainly Mothman, since my friend's aunt saw it, but 90% of this "nonfiction" book is nonsense. Keel's semi-acurate listing of the real life mystery of Mothman wins it a single star, but the speculation that he pushes as the gospel truth is laughable, and is mostly based on questionable facts and ideas that are theoretical at best. If you want to know about Mothman read James Cohen's Book of Mysterious Beasts, if you want to waste your time and Amazon's time, buy The Mothman Prophecies. 
 Polarity: Negative
True

Review: I really can't understand why all the reviewers are going crazy over this record. First off, I bought it without hearing anything by them before, but it had been highly recomended to people who like Tool and Mars Volta by Amazon!! They couln't have been any more wrong. So, why did i personally find this so painfull?Well, the whole thing in general is quite painfull. First off, the musicians. The whole band sound like studio musicians. No obvious indivuality or anything new to offer. Then we get to the vocals. The closest thing I can compare them to are Alison Moyet or Anthony and the johnsons. I don't mind Anthony and the Johnsons, but this guys vocals and the music just don't rock. Which is fine. It's ok not to rock! But why the hell, being a Tool fan and Mars volta fan, was I recomended this? It's bland, it's week, and the dubby bass, boring guitar playing/sound... weak vocals.. Actually, forget it. The whole package. It is just lame.
