I read the books a while back and remember them being pompously written, with repetitive descriptions, and the characters' main personality traits being what they wore, the kind of chewing gum they liked and how much they swore. The series has similar 'depth' and it's over reliant on you having to fill in the gaps in the plot.
The choice of the main actor was also quite predictable, although personally I imagined Forst differently, but thats only a personal opinion.
You get to see the beauty of the Polish mountains though, and if you're not too fussed about things making sense then give it a go.
