I see two ways to get out of this. One is to learn to think of those things and doing them well, even though they're not original, as part of the form. Like meter and rhyming might be part of a poem's form; it's about how you do them, not that you do them, since they're always there.

The other is to consciously decide to ratchet down your consumption of this type of entertainment and put more effort into finding things that are more "for you" -- they don't rely on the tropes you're used to. Look for foreign content, other types / genres of shows, and reduce your consumption so by the time you've watched as much as you used to in a year, several years have passed and the style has morphed a bit.
