Isle of Dogs is great! Disney+ is hardly the only place you can watch it though, and a lot of the other original Disney programming feels like Marvel-driven padding. The latest Pixar stuff is pretty mediocre relative to what they were making a decade ago, and Disney's modern films are... sketchy.

If you get a kick out of it, then more power to ya. Disney even gives you a place to put your money where your mouth is. For my money though, there's a lot more entertainment value to be found elsewhere.
