Gen 4 was Gamefreak running out of ideas, Gen 5 is Gamefreak totally redeeming themselves with MANY (not ALL) fresh, original designs, and most importantly, no old Pokemon. I seriously cannot believe people are still saying Gen 5 is bad, but yet LOVED gen 4. Almost everything in Gen 4 was either based of a (cutesy) earth animal, or was simply an evo/pre evo of a past gen monster. How is that in any way original?
Gen 5 also has some horrible crap, like another fire/fighting starter and the flying trio clones.
For the record, despite loving the first gen, I've hated many designs from it since 1998, especially Jigglypuff. Every Gen had monsters I hate, but the 4th gen had the most.
But ugh, I'm sick of both sides of this ridiculous fandom. One side says "GEN 5 SUCKS THEY DON'T LOOK LIKE POKEMON GEN 1 WAS THE BEST", the other says "SHUTUP NOSTALGIA friend TRUE FANS LOVE ALL POKEMON GEN 1 SUCKS". I think both of these groups need to STFU, and let people like what they like and hate what they hate in peace. However, the "they don't look like Pokemon" comments need to stop, because it is invalid.
And that deviantart picture linked to in here is stupid, mainly the Gyarados and Rhyhorn comments. I especially hate that "overdesign" BS. These people need to shutup just as much as the Gen 5 haters. It's like honestly, now it's the "in thing" to hate Gen 1, purely because of the Gen 5 hate.
