Final answer:
For a Netflix clone, it is most relevant to log movie-specific data like movie genre and movie rating. While user-specific data can be relevant for user profiling or communication, it doesn't necessarily need to be logged for each movie in the service.
Step-by-step explanation:
In a Netflix clone service, data points that are directly related to the movie and can enhance user experience should be logged. Therefore, it would be highly relevant to log movie genre and movie rating for each movie. These data points directly correspond to a movie's attributes and are crucial in personalizing user experience. For example, knowing the movie genre could help in recommending similar kinds of movies while the movie rating provides a glimpse into its general reception by viewers.
While user related data, like user's favorite color and user's email address, might be important for other aspects of user profiling or contacting, they do not directly relate to the characteristics of a movie and, therefore, would not be critical data points to log for each movie in the service.
