Data and Worf were the comic relief characters in the show. Think of Worf lines in the TV show like: - I am not a man - Delicious - I am not a merry man! - Good tea, nice house - I would require a Klingon woman for "companionship". - Nice legs. Er..for a human. So I don't think it was out of place to use them like that in the films. Data and Worf are probably the only characters who could pull off comic relief.
