I am about to watch Dreamcatcher for the 6th time. I absolutely love this movie. It has aliens in it, that's it for me, no need to describe more, I'm done, gonna watch it. I love the actors and have read the book. Normally I dislike Stephen King books and movies as I find them to be super cheesy, but this is different. It is genuinely terrifying and captivating. The book is highly recommended.
