It would be ideal if they wouldn't have to spend time, but just because things don't work it doesn't mean you're now entitled to take something you didn't pay for.
If the blender I bought doesn't work I should be able to take it back to store and get a refund. But just because I spent 30 minutes driving back to store, that doesn't mean I can just take another one from the shelves and walk out without paying.
It's amazing that some still don't acknowledge this point. It's the difference between 99% (or higher) [1] profit margins and less than 10% profit margins, in the case of a kitchen blender.
Even more so, the 99% profit margin isn't the whole story, as torrents are arguably more efficient (by making use of spare bandwidth among the populace). The 1% marginal costs for legally downloaded media primarily exists only because of the company's need to tightly control distribution and charge for access. With torrents, this requirement disappears and the marginal costs drop even closer to zero.
But you are allowed to, because as long as you don't greatly abuse the privilege the law will not penalize you at all.
Do while the legal system does not say he has a legally enforceable claim to watch the movie, the same system will not punish him for doing so.
Now, if we are talking morally, I'm going to guess we have different moral systems and thus not reach the same conclusion.
P.S. for the blender example, it would be more as if his purchased blender didn't work so he used a working one to turn his blender into a working copy, while the second blender continues to sit on the shelf for someone else to buy.
