FileBot

I've noticed that AMC is ignoring the scraper's capitalization and just capitalizing the first letter of each word. For instance: "The.Last.Dance.S01E08.Episode.VIII" gets renamed to "The Last Dance - 1x08 - Episode Viii"

Is there any way to make the script match the capitalization from the scraper?

That would be the default behaviour. FileBot will give you the title value unmodified as received from the API.
