Bit apprehensive at first to watch a movie with subtitles again but these type of movies/series you really need to watch in it's original language (its actually fun trying to understand words, you'll be surprised how much you'll actually pickup). It's a very good series, believable in many ways. There are nut cases out there indeed, maybe not as sophisticated as these in the series but it's filmed in a believable way. It's not about all guns blazing, it's about characters, mistakes, reality which is what makes this so good. If you're after action, car chases, explosions, machine gun fire, you're in the wrong place. If you like mystery, bit of love, bit of human relations, bit of thriller, watch it. It's not a 10 as I think there is some acting that could be improved on and maybe conclusions are sometimes a bit far fetched/too easy found, but a 9 is pretty damn high I would think.
