Very good pilot, I'm sure it will only get even better from now on. The southern gothic atmosphere was spot on, there's tons of depth and charm in the show already. Never thought much of McCouneghy, his talents never matched his looks, but sheeeeeit, he's phenomenal here.
The ending to the pilot was fantastic but the whole episode overall was awesome. Mcconaghey was on point with his mysterious/weirdo character and Harrelson was the perfect foil for him. Really interested in seeing where this show goes but judging from that first episode, looks like we're in good hands.
True Detective has apparently drawn the best numbers for a Series Premiere on HBO since Boardwalk Empire in 2010, even beating out Game of Thrones in 2011. When you consider that it was up against both the NFL playoffs and the Golden Globes, this is a pretty impressive accomplishment.
