Gen IV-
Useless pokemon get awesome evolutions, method to catch shinies more easily, first game to feature online Global Trading Station, starters are the definition of badassery, Staraptor is the coolest Normal/Flying EVER. Besides that, the Physical/Special split made pokemon whose stat distribution was previously considered to be messed up more usable and it had the most interesting legendaries and bad guy team (IMO). My only real gripe is that you needed to attach the older versions to catch so many pokemon in D/P, though they rectified that in Platinum. It also introduced stat-down berries, which made EV training SOOO much less of a hassle. LEGENDARY! (C WUT I DID THAR?)
Gen V-
Most creative looking pokemon I've ever seen. They really went all out, as they had to, in order to create a region that was entirely isolated from previous ones. This meant that none of the oldies showed up until very late in the game so the region had to had enough of it's own pokemon. My second favorite generation in terms of overall design aesthetic. The game also had the most interesting story and the bad guys weren't all just a stupidly evil group. Also introduced shops that let you EV train your pokemon for a fee. Dream world abilities also made previously worthless pokemon more useful. AWESOME!
Gen III-
Cool legendaries, cool starters, stupid bad guy team though. Introduced pokemon abilities into the game and refined the held item concept. GREAT!
Gen II-
Feraligatr was cool... But only recently became strong as he was unable to make full use of his awesome physical stats at the time. It also introduced held items, fixed the broken crit mechanics and split the Special stat into Sp.Atk and Sp.Def. And had 2 explore-able regions. NICE!
Gen I-
Boring designs and broken mechanics, but I'll cut it some slack as it was their first attempt, and it was fixed (mostly) in the next one. But it set the foundation for one of my favorite games ever. So... There's that, I guess. OKAY!
