Not sure if they're on Prime or Netflix, but I'm certain you can find somewhere to watch basically anything on the internet.

That being said here's my list of recommendations:

Peaky Blinders: Post WW I British Gangster Drama. Lot's of neat historical tidbits about the early UK Civil wars that eventually became "the troubles". So far, there's 5 seasons with a 6th in the works

Sherlock: Modern Sherlock Holmes. Really simple. 4 Seasons in total

Billions: Financial Drama revolving around a battle of wits between the State Attorney for the Southern District of New York and a Billionaire Hedge Fund Manager/owner who took advantage of 9/11 to get rich and built a web of insider trading based investors that manipulate, and I quote, "Capital the size of A European Nation's GDP". Lot's of neat bits about finance if you're into that kind of nerdery. Might actually learn a thing or two since the directors REALLY did their homework to make sure everything was realistic. Has some "slight" rainbow brigade propaganda, but it's over shadowed by all of the financial literacy and political intrigue. 5 Complete seasons with the 6th recently having begun to air.

Longmire: Modern Western revolving around a Wyoming Sheriff. Typically a classic/retro "villain of the week" format with an overarching background story that gradually builds as the series goes on. Think, Lone Ranger in Wyoming with "Silver" being an old Ford Bronco and Tonto being named Henry Sitting Bear (He's still an Indian FYI, A Cheyenne in fact.). 6 seasons in total.

Justified: Yet another Modern Western. This time based in the Cumberland Mountains of Eastern Kentucky. The protagonist this time is a US Marshall. Again, follows a mild "villain of the week" format, but the overarching plot takes a larger focus here. That being said the "Plot" is typically more based on the current season you're watching since the main protagonist, and thus goals, change each season. 6 Seasons in Total.

The Son: A really unique Western. Never really seen another series like it. Imagine if Red Dead Redemption 2 were a series. It's based around an Oil/Cattle Baron in South Texas after the Mexican-American War that resulted in full Independence for Texans as members of the USA. Lot's of plotting based around the early Oil Industry. And as a bonus, everyone's "favorite" evil oil corporation, Standard Oil, make an appearance in the second season. I personally liked all of the transitional Firearm Technology. You see Ranch hands and lawmen carry both Revolvers and early automatics like the 1911, 1908, and Luger. It's a fun little bit of history nerdery. 2 Seasons in total.

Sons of Anarchy: Modern Motorcycle Gangster series. Based around a MC club that's heavily into the Gun Trafficking industry. Set in California of all places no less. Pretty fun watch. I loathe the Club President's actor (Google Clay Morrow's actor and look at any of his tweets and you'll see what I mean), but other than that pretty fun watch. 7 seasons total.

Mayans MC: Spin off of Sons of Anarchy based around a Rival (Later Allied), MC club. I'd recommend watching SOA first, but it's not absolutely required. This one drifts a little away from the Modern Western revolving around Motorcycle clubs into a full on Gangland Drama by involving a fictional Mexican Drug Cartel with Characters Heavily Inspired by Michael Corleone from the Godfather. 3 Seasons so far.

Sopranos: Mafia Drama, almost unanimously considered one of THE best series to ever be made or aired on TV. 6 Seasons in total.

The Trust: Drama based on a Slightly fictional retelling of the Getty Grandson Kidnapping. Kind of fun if you like over the top Dramatizations of Historical events. I was also dumbfounded to find out that a lot of the "weirder" things that happen in the show turned out to be real. Like John Paul Getty having a literal harem of women in lieu of a wife. Apparently moral depravity is required to be an oil baron. Cough Rockefeller Cough. Only 1 Season.

X Files: At this point, I honestly think this might be one of the earliest known examples of predictive programming. Without giving out too many spoilers, everything we know is a lie, the government is corrupt and hiding the existence of aliens, Angels, demons, magic, etc. And at one point, a magical goo alien masquerading as a virus threatens the world. So yeah. 11 Seasons and 2 movies that tie in to events between seasons in a canonical fashion. So REALLY long watch.

Supernatural: Really good if you're into Mythology or Cryptozoology. Basically, every monster exists and the show revolves around monster hunters. Get's kind of Blasphemous towards the end of the series, and I stopped watching, but the first 10 or so seasons are really good. 15 Seasons in Total, but as I said, after a certain point I stopped watching due to the weird blasphemous tone the show took.

Revenge: Bit of an odd one, but sue me. It's a guilty pleasure. Mid 2,000s Teen angst Drama that's basically a modern retelling of the Count of Monte Cristo (One of my favorite books ever.) The main differences being the time period/setting (obviously), given it's modern day and takes place in the Hamptons in New York, and the protagonist is female. Usually I'd avoid crap like that, but this is before the massive woke feminist push, and it's basically the only good Non-Anime version of the Count of Monte Cristo (The BEST version is an anime called Gankutsuou if you're wondering). 4 Seasons in Total
