A game you "didn't know it was bad 'til people told you so"?
I'm talking about games that you still like but you had no idea were criticized so much.
The perfect example for me is Sonic Unleashed.
I admit that the game has its bad things, but I would have never imagined that it was so hated at the time... Although, that could be extended to the entire Sonic franchise, since for many years I was not aware at all of that "Sonic was never good", "Sonic had a rough transition to 3D" nonsense.
Which is funny since I've played all three of those for the first time recently, and FF7 doesn't hold up in comparison to 8 and 9. But I can see at the time how 8 could be seen poorly in comparison to 7 and 9.
