Yeah, all those people bashing certain gens are just plain rude and inconsiderate. It's okay to have a negative first impression, but at least let the pokemon grow on you before you commence bashing it. :/
It might be because I'm not wearing nostalgia goggles (Red/Blue came out when I was 11, too old to really consider it nostalgic), but I'm indifferent at worst to all the more infamous pokemon. XD
