It reminds me of the old EE 'Doc' Smith (Science Fiction) set of seven Lensman books. The last is an outlier, but for the first six books each feels like it is a similar tale as the previous ones but with the scales, powers, and threat levels turned up a notch.

Almost like having used up the ideas available, the only place to go now is incrementally growing the constituent parts. And that's how I feel about most modern action/adventure/fantasy/scifi stuff - to quote another genre: "this one goes up to 11".

But I don't want it going to 11. Even for my SF/Fantasy I want it to feel real. For me (and I know it is subjective) the author makes a good point.
