Query: starts out great, but disappoints in the end

I am a huge fan of the independent aliens and predator movies. Also, I was looking forward to the movie coming out in August. However, just to make sure I wouldn't be wasting 8 dollars on the movie, I decided to read the book, first. That way, if I didn't like the book, then I could at least get my money back.I sure was happy I made this decision because, if the book is any indication, the movie will be horrible. The screenplay has huge promise, but the script eventually unravels into some lamedrama. Everything in the plot is drivative. You'd be better offrenting predator or the original Alien movie.
