FX is killing HBO, they have the advantage of not taking on an extra subscription to access their shows. FX has requested a second season of Taboo - they may be waiting a long time. Sony paid Tom Hardy boatloads of money to save their Spiderman franchise. They fucked up with three mediocre films. Again he's being asked to rehabilitate a superhero nemesis. Topher Grace played Venom - the less said about that the better.
If Steven Knight agrees to write S2, then Hardy will return. But he's busy as well, he's writing the sequels to WW Z and the Lisabeth Salander franchises. And then there's Peaky Blinders.
Finished S3 of Fargo. I liked it. Ewan McGregor was great after I got over his accent. I wasn't familiar with Mary Elizabeth Winstead before the season, and was really impressed. Carrie Coon was excellent, but I definitely preferred her performance on this season of The Leftovers.
Personally, comparing it only to shows that aired at the same time, Better Call Saul and The Leftovers left this season of Fargo in the dust. Definitely better than S2, and still very excellent television, but obviously just not as much my jam as others.
We may have different tastes. Can't think of a superhero film I made it all the way through since the first Spider-Man (which I was obliged to not walk out of because of my company), and although I've tried, I haven't made it past a pilot in the recent shows extended Marvel or DC universe(s). Obviously, not my jam.
I quite like FX and HBO. It would be hard for me to pick a favourite or definitely say which one is better. I can definitely see why you said what you said, and I look forward to checking out Taboo and some of the others you mentioned.
But GoT, Westworld, Veep, Silicon Valley, Vice Principals, High Maintenance, and Vice are current favourites on HBO.
On the other hand, I do kind of like The Americans. And FXX is pretty much FX, so add Sunny, Archer and You're the Worst to that list.
