This thread isn't like the "Why Does Everyone hate the Third Generation" but what your overall opinion on the Generation as a whole, e.g Pokemon, Movies and of course the Games^^
My opinion: Currently it's my least Favourite Generation(4th being my Current Favourite Generation) but I still love the Games(I hate nothing Pokemon^^),
However I didnt like how many water routes there was though I did understand it was a "Water/Summer" Region.
The Pokemon designs were great with some of my Favourite's being Kecleon, Marshtomp, Legendaries etc.
Movie wise I liked all 4 Movies and thought all had great storylines.
Anime wise the Anime was an upgrade to Johto's anime just like how each new Generation's Anime is an upgrade to the previous Generation's Anime,
Storyline Wise I thought Generation 3 had a completely different storyline to Generation 2 and went deeper into some of Pokemon's past mysteries and at the same timeintroduced alot of new Legends to go with the new Legendaries.
It also introduced us to Contests which was a great addition however I get the feeling that the Generation Five Games won't have contests or that they will take a backstep to a new sidequest^^
Overall a great Generation and introduced alot of new additions to the Table(like every Pokemon Generation does)^^
