Huh...my prime only shows that I can buy Iron Man 3, not stream it for free.
I usually use Netflix and Amazon to watch old TV series (my son just finished watching every season of Star Trek Voyager). The movie selection for streaming is usually not a lot of stuff I like to watch, but occassionally there's some good stuff in there.
I so want to dump my cable but I need the HD for Patriots and Red Sox games, and my wife watches a bunch of those House Hunter type shows. I have no idea if her shows are streamed or not.
I only watch a couple network shows (Big Bang Theory, Grey's Anatomy (wife), and Arrow on CW, which I love). None of the new shows coming up really interest me that much, except maybe Agents of S.H.I.E.L.D.
Half the time I sit down with a beer to watch TV, I fall asleep anyways.
