Review can be summed up by the subject line. The book is a classic to many, many people due to it's huge cultural 80's references. I think a movie was almost a bad idea as, no matter how long it was (2h,20mins), it would never be able to be accurate to the film without removing huge chunks of the story.

And they did.

Not going to put in any spoilers but they shifted a lot of scenes around - like having the main characters meet much earlier - and also the situations of these chars. One scene, which involves a huge part of the book, they even swap which character is involved. Kind of daft when that character deliberately put themselves in that situation to try and resolve a situation. Vague, but people who've read the book and seen the movie should know what I mean.

Big race at the start was obviously just put in to do some heavy CGI for the popcorn brigade that would demand it. That's not even in the book at all, for heavens sake.

Plot lines from the book where the founder of the companies backstory was much more developed.

I could go on but I know it was always going to be a tough book to film. The movie is ok on it's own but, if you do see it, I really recommend you read the book afterwards. If you've already read the book then it's your call on seeing the film but I do suspect you will leave the cinema unsatisfied.

It's kind of like being given a cheese sandwich and then finding there's no cheese in it.
