Finding a good show to watch based on a book can be a real chore because streaming rights move around like musical chairs. Like, I was watching 'Dexter' last year, but now I have to subscribe to a different service just to finish the later seasons. It's annoying. For current big ones, check Prime Video for 'The Wheel of Time' and 'Reacher'—they're both huge and decent adaptations, though 'Wheel of Time' really picks up after the first few episodes. Hulu has 'The Handmaid's Tale,' obviously, which is still going strong and feels way too relevant sometimes. Netflix has the new 'Avatar: The Last Airbender' live-action, but honestly, I'm still hooked on 'The Sandman' and waiting for more of that. Oh, and for a weird deep cut, 'Station Eleven' is on HBO Max and it's nothing like the book but somehow just as good in its own way.
If you're into period dramas, Netflix's 'Bridgerton' still dominates the conversation, though the books are way steamier. HBO Max has the 'Game of Thrones' universe locked down, and their 'Interview with the Vampire' series is surprisingly moody and perfect. Don't forget about Apple TV+; 'Foundation' is visually stunning even if it takes liberties with Asimov. Honestly, your best approach is to pick one or two services based on the specific shows you're dying to see, because trying to subscribe to all of them is a fast track to bankruptcy.
