I would like to find out beforehand what is there. With Netflix, for example, that's not possible.
I do not think so
That's not how Disney works. They show all series and films from Marvel, Star Wars etc. The list is long.
Buy a month or do without it. That's not Netflix and Co.
There are various videos on YouTube about this.
You can simply test it for 7 days for free.
But I can tell you Disney + is worth it 😍
