There are people who will start reading this book then about 100 pages into it realize that it's going nowhere fast. Take my advice and keep reading. It gets much better, and more interesting. The ending is really good, and might have even upped this review a star.ac

This CD is great for some people, but I think a lot of other people are buying it who maybe shouldn't.For the Nirvana fanatic with money, get the full boxed set, you will probably find the DVD and the book to be worth the extra money, even if you don't listen to the added tracks.If you aren't a fanatic, stick with the albums. You will not like the low sound quality of the recordings.Now, for the Nirvana fanatic who's a bit short on cash, but absolutely has to have "Do Re Mi" as part of his collection, that's who this is for. "Do Re Mi" is an excellent track, one of Nirvana's best...so if you are a serious Nirvana fan, you DO need to have that one.

Blue Underground has done another great job with this horror / suspense movie director Argento.Great plot & suspense.The movie's main character is the beautiful and young policewoman Anna Manni (played by Dario Argento's daughter - Asia Argento) who is tracking down a violent serial killer and rapist (played by Thomas Kretschmann). Her track leads her to the Uffizi museum in Florence. There however, Anna is struck by the Stendhal Syndrome, which makes her faint, when among certain works of art, like paintings and statues. Her new handicap makes it very difficult for her to track down the killer,But she did finally found him .But i found the story a bit fantasy base but common since argento directs no comments.........long live Dario..........
