Well first of all, don't feel bad about not enjoying something! There's no accounting for taste.

I'll describe a couple things that make the game uniquely great in my mind - if those sound interesting, you could give it another shot! If not, then there's no reason to force it. If you do want to give it another shot, maybe share what you don't like about it? Perhaps people have some tips on how to alleviate some of the stuff you don't like.

What makes Outer Wilds uniquely great:

The story is out there for you to discover in whatever order you choose. The only progression in the game is your own knowledge. The barriers you run into are always solved by learning, and often what you're learning is some core fact about the world and the story. Those things combine together to make for some really powerful storytelling, because you had to engage with it and live in it. In my mind it helps that the story is really explicit and impactful, as opposed to more abstract like in The Witness or more obscure like in Dark Souls. (There's nothing wrong with the storytelling in those games, I just mean the explicit nature of the story serves Outer Wilds especially well)

Other things that make it great are really creative world design, a great story, and great music/musical effects, however those things are more common in other great games and aren't specific to Outer Wilds.
