Do you think this counts as a cliche in my script?

I am writing a script, and asked some for feed back and one person who read what I had so far, said he said that the love interest character was a cliched trope. Basically it's a crime thriller where the main character is a cop going after dangerous villains, and he has a love interest, that is sort of hos moral compass, when it comes to going too far, and what not.

I was told that she is a cliche because she has nothing to do with the actual plot, and there have been so many thrillers movies, with the love interest that has nothing to do with the actual plot. Two examples, I can think of where the love interest is not part of the plot, but a moral compass, that are similar in genre are Heat (1995), and Bullitt (1968).

But do you think it's a cliche that cheapens the character or the story in any way, because of it?
