What do you typically 'look' for in a movie?

I know this is somewhat of an open question depending on what everyones tastes are but im trying to get a 'feel' of what works and what doesnt typically speaking.

Do you prefer to get movies that have the same model in them all the way through for the entire 90 minutes or do you like to see some kind of variety?

Also, what about the 'niches' of the movies? Do you tend to buy movies that only have one specific thing happening in them or do you prefer ones with a mixture of both niches and scenes?

For me i tend to go for movies that have a mixture of things happening i think thats only because working in the adult industry online has jaded me a little though
