I'm not sure that I would be willing to pay for it separately. It has some good shows but not an astounding amount.
The interface is hot garbage that tries to upsell additional pay-for content and streaming services like Starz. Unless you know what you're looking for and go in with surgical precision, you get bogged down in a morass of upcharges.
They also started intermixing free-with-ads content and making it difficult to distinguish. My kid has started a couple movies only to get lambasted with ads every 15 mins and becoming thoroughly upset.
They recently made Amazon Music worse (you can't skip songs in playlists / radios), to force you into upgrading to Music Unlimited.
I also haven't watched a show on Amazon Video in years (Man in the High Castle was the last one).
Yet they continue increasing the cost of Prime citing those other "benefits". I wish they'd offer an a-la-carte Prime, we only make use of the free shipping one.
Idk why anyone would pay for prime anymore. They have 1 mediocre but popular show (The Boys) and pretty much nothing else relevant. There’s a decent old movie selection, but most are rentable a la cart for $3.
And the shipping is never 2 days. I’m not even convinced it’s faster than non-prime shipping.
And certainly no one is doing it for the music service.
Prime-affiliated services (Prime Video, Amazon Music, etc.) exist to make Prime more sticky and keep you in the ecosystem.
Walmart is doing something similar with, IIRC, Paramount+.
