I played The Witness and didn't find it remotely fun. I've enjoyed all of Blow's other titles.
I suppose I was coming in with expectations of a modern Myst and/or Riven, but it was not that.
There was not enough active narrative to keep me engaged with the puzzles and there wasn't enough "reward" in completing them.
I thoroughly enjoyed The Witness, but it nearly collapsed under the weight of its own pretentiousness. Especially to your point, what counted as a "narrative".
Interesting. Being in that world was deeply captivating for me. Every time I've played that game I've experienced a jolt of creative drive.

If that was your expectation going in I can definitely understand you feeling underwhelmed.
That said, you may still enjoy The Looker...
I enjoyed the Witness to a degree.

I did not notice the environmental puzzles, even after the obvious one at the top of the mountain looking down. I didn't get that that wasn't a one off. Someone had to point them out. I've had other friends who also missed that. It's arguably the game's single biggest reveal / surprise. It was pretty amazing!
That said, only found maybe 20 of them and was not compelled to keep looking for all of the rest.
He was focused on creating a very particular feeling of epiphany as an artistic statement, and I think he succeeded at that. Is the game not especially fun? Is it perhaps overlong? Probably? But I can think of very few, if any, games that provided the very particular feeling that The Witness provided in those moments that I felt it -- the feeling of the world opening up with new possibilities and interpretations.

I loathed Myst, so had avoided The Witness for the same reason you played it; I'll maybe give it a try now.

All the more reason to try the Looker!

"All other titles" would be just Braid, no?
