I tried to watch some of the stuff they were heavily promoting, but couldn't get into them. Shining Girls is really bad. Tehran, a 3rd-party adaptation from Israel, is Netflix-grade trash that strains one's ability to suspend disbelief. Adding Glenn Close, an elderly American WASP, as a Mossad agent, did nothing to make this weird Israeli propaganda vehicle more believable.
Anyway these are all matters of taste but objectively I believe Apple TV+ has very few subs, which was my main point. It doesn't seem like a massive advertising opportunity.
