First of all, I loved the movie. And I do believe it was misunderstood by the wider audience who expected something completely different. The movie rocked, no matter what some critics may say.
Now, about the book. I'm torn. I'll start with the pros:
- the book is extremely faithful to the movie, what is especially notable as it was being written while the movie was being shot. When you read it, you can see the movie playing in your mind's eye. That's nice.
- There is one (if I'm not mistaken) extra scene and a handful of other scenes extended.
- Adds more clarification to some elements of the plot that might have escaped the audience, especially during the first viewing of the movie (and all you x-philes know what I mean ;))
- Tries to tie The X Files history (Samantha, William) to the events taking place in the movie.
Ok... And now cons..
- I can't honestly say the book is well written. Some sentences and descriptions are actually bordering on being childish, as if I was reading a 10-year-old's essay on the movie.
- Weird syntax and use of italics. Bad editing job. I'm pretty sure there are grammar mistakes. I was actually surprised to see the author having received some awards. Hopefully the writing he received them for was better.
- The paragraphs that are not part of the story, but supposed to explain X Files history seem like they were thrown in at the very end, just for the heck of it. They do not read well.
Over all, I don't regret buying the book. It'll be nice to reach for it sometime in the future. Good treat for the fans, especially after such a long period of depravation.
