Before season one aired I had never seen anything so compelling in storytelling or filmmaking in my entire life. The following two seasons are watchable and well-made but nowhere near as phenomenal as season one. This is a paint-by-numbers example of how to do a gripping and unique story. There is nothing negative I can say about season one. Everything is top-notch. The acting, the story, the camera work, the music, the mood, everything.
We see through the relationship of the two main characters a complicated and sometimes volatile relationship. They aren't enemies but they aren't exactly friends either. The dialogues they share together are some of the most interesting filmmaking I've ever seen. They aren't good men or bad men either. They exist in the grey area. They are just good enough to not be bad but bad enough to not be good. They are stark contrasts of one another as well. The relationship Rust and Marty have evolves constantly throughout the series and is the highlight of the entire show. I cannot recommend this season enough.
