Cliché is a noun, not an adjective. Originally it meant a phrase so often used that it was set up as a permanent metal type-block called a cliché. Something can be clichéd but it cannot be cliché. It can, of course, be a cliché.
Critique is a noun, not a verb. You cannot “critique” something, though you can make a critique of it.
Different: Things differ from things. They do not differ to them or than them. The only correct usage is “different from”.
Key: It is not true to say that “key” is not an adjective. We may say “__ is a key question”. However we may not say that “__ is key”. In other words, key may be used attributively but not predicatively.
Nuance is purely a noun. Things can have nuances but cannot be “nuanced”.
