This is a general trend in media as a whole today - sequels, reboots, remakes/remasters, derivatives of other popular media are just as bad in television and video games. The only saving grace of "TV" is Netflix, Amazon and HBO who are more willing to take the risk on new IP.

The last AAA video game I purchased that wasn't based on an existing IP or derivative of a specific formula (see: Ubisoft) was Titanfall. The last movie I saw for myself (and not my daughter) that wasn't based on existing IP I can't even remember, it must have been Grindhouse (Planet Terror / Death Proof). Meanwhile, the last serialized "TV" content I've watched that wasn't a new season of an existing show or a spinoff was Transparent, before that there was Orange is the New Black, House of Cards, etc.

I would love for some fresh ideas in the available content out there, but it seems like executives are especially adverse to risk considering the budget it takes to make "current-gen" visuals in blockbusters or AAA video games - and I wonder if that is why serialized shows are where most of the "fresh" content is considering people expect lower production values out of a 20 episode season of 45 minute episodes.
