TIL that In 2018, A hacker broke into people’s routers (100,000 of them) and patched their vulnerabilities up so that they couldn’t be abused by other hackers.
I stopped after Season 4. I wanted to wait until the whole thing was out and then binge the hell out of it for a couple days. After that last season, I've never felt the need to continue. Although I'm pretty sure the next season or two are fine.
I think up to season 5 are fine. Season 6 is starts the downhill trash spiral. Season 5 also ends well enough you could watch until that point and move on with your life. A few holes left but your own imagination would be a better ending.
