I don't think Gates to Infinity was "hated," per se, but more like it kinda left much to be desired. The game lacked the large amount of content that the previous games possessed, with the giant reduction in Pokémon availability hurting it the most. And as if that wasn't enough, the large cut in starter choices basically rubbed salt on the wound. As for the story, it wasn't "bad," but it just didn't live up to the Explorers titles (which is understandable because that would be really hard to accomplish).
