I think the parent comment is referring to the abundance of comic book derivatives, sequels and uninspired remakes that have become increasingly prevalent of late.
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.
"For $200 million, we can guarantee return of $1 billion."
"Nah."
People aren't adverse to trying new things but the movie industry is pretty risk adverse. And as for people being tired of the reboots and remakes the answer is mixed but easy to see in box office returns. Rehashing old ground is fine so long as it's good or is fun to watch. Until these movies start failing en mass industry will keep making them.
