There are people who hated 5th gen that much? I've been playing since Red and Blue when i was little, so while I do have some Nostalgia for the 1st and 2nd Gens, I loved gen 5! The only gen I really 'hated' in a sense was Gen 3. I really was not fond of too many pokemon from that gen. I mean, I liked Absol and Tropius' designs, that was it. I hated all 3 starters from that gen, but even then I never questioned their creativity. I just thought that maybe I was growing out of it or something. Then Gen 4 came along and I loved the, so I knew it was just a fluke lol.
Apparently Im also in the minority for Gen 3; it seems most people love that gen. I hated all 3 starters and most pokemon from there, but to each their own lol.
