Lacks the intelligence of the first movie
The most shocking fact about CDII is its stylistic turnaround from the first movie.
While CD1 was a sharp social satire CDII is a contrived action comedy full of tired movie cliches.
In the first movie all the characters' motivations made sense with both protagonists overcoming their fears and prejudices by their mutual affection. In short a very clever love story.
In CD2 each protagonist simply looks for the easy way out of his/her problems; firstly Sue who submissively obliges to the Colombians demands and secondly Mick who lures the gangsters back to his outback home.
So essentially both revert back to the roles they started out as in the first movie, undoing all the previous development they experienced.
