One of the things scriptwriters need to know is how the real world works. In this case the sacking of the main character, Martin Pyrite, is completely unbelievable. No business would ever act this way, they'd be sued and would be bound to lose. The poor quality and unreality of that event taints the rest of the film, and I could only watch intermittently. I only watched in the first place to see Neve Campbell, an interesting actress. She's not in it much and again that gives the film away. A well-known actress paid a lot for a small amount of work - it's window-dressing - to get the film off the ground. One to avoid.
