After hours of questioning by the police, the suspect finally 'cracked'. [=finally told the police what they wanted to know]
The new restaurant 'is not all it's cracked up to be'. When we went, the service was awful and our food was cold.
Is the movie really 'all it's cracked up to be'? = Is it really 'as good as it's cracked up to be'?
