I recently completed all 4 seasons of Goliath, watching S1 again as that's all I'd seen previously. Prior to that I'd just re-watched the first season of Fargo, too, having only seen season 1 previously. In both cases the high IMDB scores were gleaned from the first seasons alone.
I really enjoy Billy Bob Thornton ever since I saw him as the mechanic in U-Turn, which is an extremely frustrating movie, but also an immensely enjoyable one.
Regarding Fargo the first season was excellent and well deserving of its high vote status, but subsequent seasons not so. BBT only featured in S1 of Fargo and I'd give that 9/10. S2 7/10, S3, 3/10 S4 gave up after episode one as it was garbage.
In Goliath again the first season was excellent and well worthy of another 9/10. S2 6/10, S3 3/10, S4 2/10. I became so frustrated with the need to be shown inside the character's dreams, hallucinations, minds and thoughts. Stop spelling things out to me like I'm in possession of a juvenile mind!
I've just finished watching the first season of The Responder, with Martin Freeman. Freeman was very good indeed. 8/10 from me.
