Well, it probably depends on what you're doing. I'm interested in creating fiction and comedy, so, to me when I'm watching shows I'm entertained, but I'm also studying them to see what works and what doesn't; how they approached certain problems, etc. But realistically, a lot of people aren't interested in creative fields, and in that context sure, watching fiction can just be hedonism in a sense. I like to think good fiction and comedy actually teaches you something, though, but in a way where it doesn't feel laborious. For instance, standup comedy might just seem like laughs, but the comedians that are really good at it almost always have a kernel of truth in what they're saying, and comedy is one of the best ways to say something controversial without getting crucified.
