What Causes Zombies? . A sailboat arrives in New York Harbor.  It seems abandoned but a coast guard member is killed by a man on board.  The man is shot and falls into the harbor.  The boat belongs to a man whose daughter is concerned about him.  She and a reporter hire a boat to find her father.  Their destination is an island said to be cursed.  The boat they hire is run by a young couple.  Along the way the couple do some diving (she is topless).  She is scared when she sees a man under the water who attacks a shark and tries to eat it.  She is very upset and somehow loses the rest of her suit when removing her tanks.  The Continue to the island which is just a short distance away.    Once on the island they discover researchers looking into a phenomena where the dead rise to attack the living.  Legend says it is the work of voodoo but the lead scientist is convinced there is a medical explanation.  Unfortunately the missing father has already died but at least now it is known.  But soon the zombie trouble gets out of control as cemeteries give up hordes of the walking dead.  In the end, only a few manage to escape the island to head back to civilization.  They keep one zombie as proof that they are not crazy.    This is one of the better zombie films although the final battle is a little odd as zombies seem to appear out of nowhere inside buildings.  That aside the story builds nicely with the multiple plots weaving together smoothly.  There is plenty of nudity in this one and plenty of gore, although somewhat tame by today's standards.  The acting is reasonable for the effort and special effects are decent.  I enjoyed the ending which I gather was supposed to be a shocker but which I predicted from the beginning.  My guess is that most viewers will get too caught up in the rest of the movie to think that far ahead, or so the producers hoped.  If you like zombie films you will have to check this one out

Complete butchering of a good story . I had never seen Queen of the Damned until last night, when I had just finished Anne Rice's novel Queen of the Damned.  Knowing I would soon be done with the novel, I was curious to see the movie so I went out to MovieStop and picked up a cheap, used dvd copy, despite hearing that this movie was very bad.  Turns out, the word bad is an understatement.    Let me get to the point, there were several changes in the story, and I understand that some of this needs to be done in the movies for screen time reasons, etc.  But I found that after reading the novel, while the basic premise of the story is the same as in the novel, pretty much everything that gave the novel's plotline it's depth and intrigue was removed from the story in the film adaptation, and this movie simply falls flat.  I was shaking my head by the end of the movie with such disappointment that so much of the story was hacked away.  The vampires in this movie are not portrayed with the amount of love & feeling that is intended by Anne Rice, Akasha included.  Maharet, perhaps the foremost character in the novel, basically doesn't show up until the end of the movie simply to take part in a disappointing final showdown.  Again, all of the backstory that should have been present here was missing.    I won't spoil it for any of those who still plan to read the novel, but Akasha's motives for what she was planning to do were actually logical (in her own evil and misguided way), but there was a reason for it that she saw as legitemate, where as in the movie it was simply "everybody must die!".  Period.  That's your motive for everything that the movie was building up to.  I can't stress this enough - the depth of the book is GONE in the movie.    Like I said, I understand that things need to be trimmed/skipped for the sake of screen time, etc., but this movie was barely over 1 1/2 hours long, and so much of the plot development could still have been included here to give this movie the depth that it lacked.  What's wrong with adding even another 30-45 minutes of screen time to fill in the story and make it a 120 or 135 minute film?  Heck, I sat in the theatres for all three Lord of the Rings movies which all ran over 3 hours.  Or was this movie directed at punk kids with 10 minute attention spans, rather than the fans of Anne Rice's Vampire Chronicles?  Such a shame, because this movie really had the potential to equal, if not better, the adaptation of Interview With the Vampire.    I could go on and on about the other things that were done in this movie that I thought were just stupid, silly, etc. etc.  Kind of like how the other vampires were pissed at Lestat for revealing himself to the world as a vampire and giving away vampiric secrets, yet they decide to fly up on stage during the middle of the concert, in front of tens of thousands of people and start fighting, in essence "revealing" themselves as well, which is totally inconsistent with why these vampires were angry in the first place.  I won't go into all of the details, because it would take too much writing to tell you everything that bugged me.    Bottom line, I guess if you're into cheesy vampire action flicks with a Korn, etc. movie score, then you may still see some value here, but Anne Rice diehards will most certainly find this movie a waste of their time.  But don't let this movie scare you out of reading the novel, because the book is much much MUCH better than this movie

Sleeping Pill!  Not a workout! . This is the most boring, unmotivating, uninteresting workout I have ever owned, yoga or other.  I am exceptionally disappointed, as it was voted best workout DVD of 2005 by Self magazine. I have only been practicing for a few weeks, having fallen in love with Fit Tv's Namaste workouts, I expected the same great music, flowing rhythm, and steady pace.  Instead, this is an incredibly slow-moving, dull workout that doesn't even challenge me, a true beginner.  I adore yoga, and wanted a longer, challenging workout--this is not it.  I'm back to my FREE FitTv Namaste workouts, until I can find somethng better
