I think there is a little bit of a difference between underrated games and games that you like but everyone else hates. For instance, I think Klonoa is a highly underrated game, but I can't find hardly anyone who HATES it.
But a good example of a game that I like that eveyrone else seems to hate is Pokemon Channel. I loved this game, and many people put it on their 'worst Pokemon game' lists, even though I can think of far worse ones, like Hey You, Pikachu! and Pokemon Dash. I I just love the creativity of the game where all you do is watch TV with Pikachu!
It has elements of Animal Crossing in that you can decorate your room. It's like a classic game compiliation because you can get versions of Game & Watch style mini-games that were actually released in stores called Pokemon Mini. The exclusive cartoon you could unlock was cute, and I just like how they made a whole game out of an early GameCube tech demo (Meowth's Party). The whole experience just made me smile. It was like a children's activity book come to life. That makes it also great for little kids.
