Took a long time, but finally finished Peaky Blinders. I struggled a bit through seasons 3-5 as they kept ratcheting up the global politics angle for a neighborhood kingpin. Production quality remained high, I just don’t know the history of the era to be in tune with facial movements, the IRA at the time, etc. I just hung on, taking their word for it that this was semi-accurate and plausible.
That said, I really dragged out watching the back half of s5 and all of s6, mostly because I had no feel for where it was going until they crystallized Tommy’s end game. Which, I kinda liked, because it was feeling like a very meh ending on the horizon. Then the end twist was fantastic.
Would I recommend the series? Yes. Invest 2-3 seasons, see if it hooks for you or not. The ending is solid, without committing to anything.
