Sure, and with good reason, in the sense that most of what gets labeled "entertainment" is really terrible. We get the entertainment we deserve. To me, being entertained is having your mind engaged with the work of art on multiple levels. So I think a lot of what gets passed off as entertainment really does not qualify for that definition. It's merely diverting at most.
To be entertained by something is in turn to entertain it, like you entertain ideas, a kind of mutuality there that I think is part of my definition of "entertainment," that you're giving back to the work at the same time the work is giving to you.
