I &#x27;rent&#x27; quite a few movies from iTunes, Amazon, and Verizon.<p>iTunes is generally botched because, as others mention, it requires full download and thus is generally a pain in the ass.  Verizon makes it difficult to watch anywhere but my TV. Amazon (though relatively good on my FireTV) doesn&#x27;t work well on my iPad.<p>More fundamentally: none release movies fast enough. And, when they do, they require me to &#x27;buy&#x27; before they allow me to &#x27;rent&#x27;, several weeks later. Fortunately, most movies from the last decade have been garbage. But, when something truly great comes out, I have to resort to the black market to get my fix.<p>Luckily, we have economic principles to fill the gap.  Supply and demand.
