Watched 1-2 things on it..
As other have said.. the selection is very.. MEH.
Only semi decent thing i have seen on it, is that the actually appear to have Simulcasts of a bunch of CURRENT Anime on it.
The one thing i like the most about it (Well this applies to the web interface, not sure if it carries over to any other apps as well? Havent tested), is the age catagory PASSWORD lock.
Now, i know things like netflix, etc have the profiles. Where you can say a profile is kids, etc.. semi narrows the content, etc. But you can easily just switch profiles, etc. And the kids narrowing, is pretty broad.
Only the one profile with Prime (that i see), but you can lock things to specific ratings.
So say, anything above PG13? Requires a password to view.
I would love to see this implemented in other streaming services.
