On the whole streaming wars thing, Amazon is my favorite at the moment and in my opinion by far and away the best of the lot.
The Expanse and The Boys are excellent and then they come up with stuff like Tales from the Loop, Too Old to Die Young and the upcoming The Underground Railroad (Berry Jenkins).
They will really come into their own with the LOTR show, its going to be massive. The second age is the perfect backdrop and the synopsis that released is pitch perfect. And then on top of it they have Wheel of Time series as well. These two should lift them to the top tier. Add the Boys spinoff, a potential Ringworld show and they are the ones to beat for me. They could have had Culture too but sadly it didn't pan out (I am still gutted, hopefully one day).
Netflix do have enough to keep me going. Bly Manor was terrific. And I am pretty excited about some of their upcoming slate especially with The Three Body Problem announcement.
HBO while they do have a great library and properties like DC, GoT, Dune and Harry Potter but so far they have been all over the place. Simply put they need that disney plus moment.
