I do know that Generation 3 and 4 are the most hated. Now, whether that is because they are succeeding Gen 1+2, I don't know. But, I loved Generation 4. Most of the problems with it were fixed in Platinum which I enjoy more than any other game in the series with the exception of HGSS. I love the region, the characters, the Pokemon, everything just kicks major ***, and since I know people will hate me for this... I think of it as better than Gen 5. Yes, I think Gen 5 had a bland region, bland characters, boring Gym Leaders, and terrible and samey Pokemon ideas, and the music just made me cringe. To this day Platinum has my favourite soundtrack out of every Pokemon game ever.
