Instead of a Lord of the Rings series, Amazon should make an adaptation of Dungeons and Dragons.
An hour-long "adventuring procedural". Main cast of 6-ish characters with different skills who work together to solve a new "quest" each episode. Think of it like CSI: Baldur's Gate! Reflects both the structure of weekly tabletop role-playing sessions and the sorts of problems/solutions you might use in the DnD rules.
