True Detective is an absolutely incredible crime series. I've had to come back and revise my original comment because they just released season 4 so I had to include that in my comment. Like most others here have already said, Season 1 was on a different level. It was so good, so original and so incredibly acted, written, directed, etc that it was hard for the other seasons to live up to that first season. Season 2, even though it had an amazing cast, was not very good at all and easily the weakest of them. Season 3 was better and absolutely worth watching. Now, season 4 just ended and it was fantastic. I couldn't stop watching, I waited to the end of the season before I started it so I can binge it and I'm glad I did because that's the best way to watch it. Every season is different with a different story and a different cast so you don't have to watch in order. I absolutely recommend you watch season 1 and 4 though. If you have the time you can watch season 3 without being disappointed but skip season 2 all together.
