It's a good rule of thumb not to say anything that can be misconstrued as disparaging about a person in mixed company. Especially on the internet.
Far too many people have crossed the line from criticizing a movie or show to attacking the person who made it, so people are quick to take offense these days. Especially if you use a word or phrase that has negative connotations.

I liked the CW movie, but YMMV.
