Well, I'm Brazilian and my English is not the best, so I apologize for any mistakes.
I start by saying that one thing I don't really understand is why people lower the rating given to a show just because the last season is weaker, even more being seasons with practically independent stories, where you can abandon the last season if you don't like it, because it will not interfere with the others. My rating here is 9/10 because Fargo brings so many sensational things in the first three seasons that it does not deserve a downgrade due to the fourth season. Especially because the fourth season, despite being full of problems, has some wonderful moments.
Fargo is simply the best TV series I have ever seen in my life. The first two seasons are brutal criminal stories permeated with black humor and coincidences typical of a comedy of errors, but full of philosophical, religious, cultural, political, social, economic and historical references. The third season still follows the same line, but with a little less black humor and comedy, and investing once and for all in the moral, philosophical, religious and even spiritual aspects. In these three seasons we can see the conflict between good and evil, the evil being represented by figures with clear references in mephistoles.
In my opinion, the fourth season lost a lot of the essence of the series, in addition to having a confusing and dragged script, but even so it presented moments of historical and cultural references of great quality, the highlight being episode 9, a masterpiece, all done on top of "The Wizard of Oz", "Alice in Wonderland" and other children's stories with the theme of a lost child somewhere far from home.
I highly recommend this series and I suggest you watch it trying to capture all the details, like the real natural phenomenon of fish rain, which is shown in the first season, or the Val Johnson incident with flying saucer and the beginning of Ronald Reagan's Alzheimer's in season two, as well as all biblical and religious references, already beginning with the evil speaking of the Garden of Eden in the first season. Oh, don't forget to also look in the independent stories of each season that you are watching for references to previous seasons. Ex: the second season showed you the origin of Mr. Tripoli, Mr. Wrench and Mr. Numbers from the first season, did you notice?
Finally, I would like to praise the excellent work of production, direction and setting of each season, as well as the acting: Billy Bob Thornton, Martin Freeman, Kirsten Dunst, Ewan McGregor, Mary Elizabeth Winstead and Daniel Thewlis are spectacular.

* I wrote this review in 2021, after watching the 4th season, now I come back here almost 3 years later, as I just watched the 5th season: even though it didn't maintain the level of the first 3 seasons, there was already a clear improvement compared to the 4th, which was the most inconsistent of all. Superb performances from a wonderful cast, beautiful photography and soundtrack, engaging characters and a typical Fargo story. The closing episode simply brought tears to my eyes.
Season 5 - rate 8/10 - Highest point: the last episode (10).
