Yes but presumably that cell has content fetched from a server right (title, actor names, title image which itself is dynamic based on Netflix A/B testing scheme, etc.)? Wouldn't it be faster to just get the content from the server ad hoc? I'm thinking you'd also potentially have a lot more network overhead if you preload the cells because then if a user doesn't scroll to one of these cells you've created them and they aren't used, and you've fetched server content too.
How many cells would you create? I guess maybe Netflix has a default limit per category of titles they would display?
