I just signed in to Apple’s 3 month offer for the purchase of a new device. The first movie I wanted to see I had to rent or buy. With the exception of Disney’s cinema previews, none of the others wants me to rent while I subscribe (I assume having the 3 month free does not make a difference with regards to rental content). This was a total “nope” experience.
Switching to Apple TV productions only, I felt that the service would not hold me more than a few days.
In fairness, these days none of the streaming services can capture me. I subscribe for a month per year to Netflix to catch up. And while I really like a lot of their shows, it also quickly shows, how shallow many productions have become, especially feature movies. However, when first we tried it, Netflix held us for a year or two before we felt time is spent better without streaming.
HBO and Disney only made it a month or two. Disney is just too repetitive in new productions. They do create a lot, but it just does not attract us any longer.
So it is true that this jump-in-and-leave applies to all services, but at least to me Apple felt the least interesting.
