Whenever someone says online that something's declining (Hollywood movies, video games, UX experiences in desktop environments, etc.), I see a variation on this argument: "actually the options are even better today, they're just buried" (often accompanied by: "you were just younger then and everything was new and that's why you liked it").

Sometimes, cultural decline actually does happen, usually eventually followed by some kind of renaissance. Anyone who has studied the cinema, literature, etc. of a certain country in the past knows that there are "hot" periods and "cool" ones. When we see this phenomenon in the past, it doesn't tend to trigger the same defensive reaction, I guess because it doesn't feel as personal.
