What does this match mean on Netflix?

Which means if the number is always higher

I think it means how much it matches the series / films you have otherwise watched and the higher the number the more likely it is that you like the film or series

Nothing at all

An algorithm is running in the background that monitors your visual behavior.

So Netflix suggests series and films that you judge based on your viewing behavior.

The higher the%, the more likely you are to like The Movie or Series.

A little tip: If you want to be offered more films and series that you might like, then rate series and films that you have already seen to feed the algorithm.

The more reviews you give (both positive and negative), the better he "gets to know you" 😅
