I first saw this movie when it was shown as a mini series on TV. It has done a good job of following the main story line of the book. David Birney does a great job as Dr. Jonathan Ferrier. Well worth the price. It may seem a little long before you start watching it, but you will be so caught up in the story that you won't notice the time at all and it is on two discs so you can take a break if you need one.
