It's just very difficult to explain what is so good about the game without spoiling the heck out of it, and since a big part of the experience is discovery, people that really like the game will hate do not want to spoil it for new players.
I play puzzle hunts, and have played a whole lot of puzzle based games over the years. I do not like Braid that much. However, I think The Witness is, gameplay wise, better than Portal, Talos Principle, Myst, 7th Guest or anything from the Professor Layton series. The puzzles get to be very hard, but they never felt unfair.
If anything, the negative reviews come from how the very beginning of the game starts too slowly, making sure you understand a little piece of the game, when, in practice, there's a whole lot more to it. The tutorial area is simple and generic, on purpose. Right afterwards, you get to an area that is just confusing, with puzzles you really shouldn't even attempt. Go anywhere else though, and the real game opens up, and it's wonderful.
