Greetings from Lithuania.
Episode 5 was 8/10, and episode 6 was solid 9/10. While both of them moved a kinda complicated story so far forward, they did it in a bit different way. While the script is in the same mood, and didn't feature some groundbreaking plot points, directing was better in episode 6, director Miguel Sapochnik (still fresh from milestone "Game of Thrones" episode "Hardhome") did it better.
Overall, while this season's main plot isn't as intriguing as 1-st seasons yet, nor it isn't boring. Actors (especialy Colin Farrell) does a great job (while Taylor Kitsch's character isn't really used well), there are some scenes that are simply great - like for example the one in prison and the whole ending in party house. Still i can't figure it out "what" "True Detective" show really is (after seeing now 14 episodes of this anthology series - it is partly a detective story, with strong main characters which are out of their luck in personal life, but they are true detectives. It has some dialogs that would have never been spoken in real life (except for in some philosophy lecture), and it is not a gritty crime detective, yet it features the dark side of the world and human nature - "man is the clueless animal", but it does't go to deep. Maybe trying to enjoy it just the scenes them self, while you "get the beat", but then in your way stands a confusing and not typically simply told plot (which isn't a minus).If creators would manage to merge difficult plot (as it is now) with superb and not oversimplified but intriguing narrative (which isn't now) and deep and rich character (yes and no now) - that would be probably a near masterpiece. At the moment i can say that we don't have "a season we deserve" (in comparing to 1-st season), but it's is very OK one and definitely a watchable one (and sometimes in between great one). Nevetheless, last two episodes will be wild ride i think.
