If you expand cliche to include idiomatic phrases then doesn't that render most phrases cliche?

Cold Winters
Harsh Springs
Summer nights
Dark Moon

Also, does the existence of an idiom within a phrase render the entire phrase cliche? It would make it very difficult to write anything original, n'est c'est pas?

For example, if I use the phrase:

"My broken heart is a broken clock, stuck at half past twelve."

Does the use of the idiom "broken heart" render the entire phrase as cliche?
