I guess I didn't remember the specifics of the conversation that well. In general, the idea of blatantly copying something is bad to me, and whoever's doing it definitely loses style points. But as I said, what it comes down to is whether or not I enjoy the final product. Hell, there are 1000 different pizza places here in the Chicago area. Do I care that every single one of them is making something that they didn't invent? Nope. I just order the pizza I like. Same with any food, or movie, or whatever. I care whether or not I enjoy it.
Now, there will be cases where my awareness that something is literally copied from something else will affect my enjoyment of it. If I can't watch a certain scene from a movie without it reminding me of the exact same thing happening in some other movie, that can be distracting. And if it's so distracting that I can't enjoy the scene, then there it is, I don't like it. But I don't dislike something simply because it copies something else. I can still enjoy the final result.
