Der Kameramörder

First off: good production values and acting.

But the script? Everything that made the book memorable, its main plot points, its mental core - is completely missing from the movie. Instead, you get some run-of-the-mill thriller fare. Which is forgettable, a waste of time.

The main point of the book was the interaction of media with murder, that media need and want murder for sensations - and some murderers want media to show their "works", providing them with the incentive to kill in the first place. And some lines of thought starting from that.

Did you find any of this in this movie? Guessed so.

So, 1 for the script, 7 for production and acting, results in 4 overall.

Avoid it, read the book instead.
