Games everybody seem to love but you just can't get the hang of it

I think the title is pretty straightforward: games that everybody loves, you can (almost) only hear good things about it, how great it is, but when you get to the point to try it, you're like..what's the big fuss about this?

For me it's definetly Crypt of the NecroDancer. 98% positive reviews on steam, 88% metacritic score, and lately I managed to give it a shot and honestly I just don't get it. Jump around and attack to the beat and that's it? Am I missing something? (and before someone goes nuts I'm not saying it's bad or anything, I just really don't get it)

So, what's the game that everybody goes nuts for and you just don't see why?
