That is a bullshit comparison. Most of those films are available for RENTAL or PURCHASE on Amazon, not as a part Prime video. You might as well compare Netflix to Amazon's DVD/Blu-Ray selection while you're at it.
We may be talking past each other. Here's my line of thinking:
"Hmm, $(MOVIE) sounds like it might be pretty good. I'll give it a try. Bummer, not available on Netflix. Bummer, not available for free on Amazon. But they'll let me watch it for 48 hours for $3.99. Fine, whatever."
Here's yours, which is apparently shared with quite a few other people in this thread:
"Hmm, $(MOVIE) sounds like it might be pretty good. I'll give it a try. Bummer, not available on Netflix. Bummer, not available for free on Amazon. Wait, OMGWTFBBQ WHAT IS THIS BULLSHIT? $3.99 FOR A DRM-INFECTED STREAM THAT PROBABLY WON'T PLAY ON THE OVERCLOCKED PDP-11 I BOUGHT ON EBAY AND INSTALLED LUNIX ON? FUCK YOU JEFF BEZOS I'M TELLING RICHARD STALLMAN ON YOU"
One of us gets to watch the movie. The other gets admitted to the ER ahead of the guy with the broken collarbone and the lady whose kids have the flu, because hey, it's not every day they see a 260/195 blood pressure reading
