You still have to find which service it's available on, enter payment information, download an app... And even then if you're not in the USA the selection is distributed across more apps, and lots of content isn't available easily even if you want to pay.
That's Amazon AFAIK, I don't know of any others. It's a step in the right direction but the price is still too high (it's usually $4-$5 in my experience). I only get to watch it once, not keep it, and I pay you double what I used to pay Blockbuster? No thanks.
Blockbuster new releases were $3 in 1990 dollars ($6.60 today). This was in a mid-sized town in the midwest, not Manhattan or LA. Blockbuster was also far less convenient.
