I have fantastic news in Movie Night stuff and Growing Together cross-compatibility!
The favorite movie your sim has declared will affect how much they'll enjoy the movie in the movie theatre. Drama is a one extra genre though, so that is an exception here, but still a positive surprise. Also, kids movies unfortunately don't seem to be like family movies, so declaring family movies to be favorite genre doesn't affect the outcome.
Traits will also affect how sims enjoy the cinema movie (with + meaning likes and - meaning dislikes). Here's the list under the spoilers!
Unflirty - (unless they've declared Romance as their favorite movie genre)
Kids
Childish +
Cheerful +
Hates Children -
Horror
Gloomy +
Geek +
Evil +
Squeamish - (unless they've declared Horror as their favorite movie genre)
Cheerful - (unless they've declared Horror as their favorite movie genre)
Drama
Art Lover +
Creative +
Childish -
Action
Active +
Bro +
Snob - (unless they've declared Action as their favorite movie genre)
Comedy
Goofball +
Clumsy +
Bro - (unless they've declared Comedy as their favorite movie genre)
Snob - (unless they've declared Comedy as their favorite movie genre)
In addition, emotions also affect the outcome, as negative emotions make sims like the movie less and positive emotions make sims like the movie more. In addition, sims banned from the movie theater will never enjoy the movie.
You know what, as I have the files open, why don't I also put all the potential movie titles here. Under the spoilers, of course:
