If the very large number took hundreds of people and millions of dollars to come up with, and it brings you pleasure, then yes, merely copying it when it's legally available for rent is wrong. Obviously stealing physical things is different from stealing digital things, but they are both fundamentally wrong because by doing so you're denying the creators the return on their investment. The manufacturing (copying) cost for digital content being 0 doesn't really matter; it just means that the net cost of production is front-loaded. I can invest $30,000,000 in a housing complex with a tangible amount of units, or a Hollywood movie with infinite "units". I still deserve to get a return on my investment.
