I don't. I embrace them.
There is a reason why some ideas take, and others don't. That's because those ideas are generally well-liked and resonate with audiences. The key thing is to avoid cliched speech. But building stories around tested ideas is good storytelling; there are no new ideas under the sun, only subverted or reimagined versions of the same ol' same ol'.
Don't believe me? Go to tvtropes.org. It is one resource I consult constantly when I'm writing to come up with ideas of where things can go (by looking at how they typically go, subverting some tropes, adapting others).
Every character in the original trilogy is a blatant cliche character. They are all great characters.
Every character in the prequel trilogy is an over-wrought, whiney drama queen. They are all horrible characters.
