The Pokemon designs have been progressively getting exponentially worse. In the Pokemon, in the Character art, in the level construction, in the gym balancing, in the story writing. As of Generation 5, the overall quality has plummeted. I was actually outraged by the Elite 4 in Generation 5. It was a self contained square of permanently useless Pokemon types that were all weak too the same things they were strong against, and the lack of sequentiality took away any sense of tension as they were all as useless as everyone else instead if it getting more difficult has you progressed. The story actually had the potential to be something really amazing forcing players to re-examine their relationships with their Pokemon and whether or not battling was okay, but then it undermines its own story and handles the topic in a childish and incompetent manner (opting to simply discredit the pro-Pokemon rights side instead of actually giving closure to the argument). The Pokemon are just plain hideous, with some of the most idiotic looking designs I've ever seen. Swwoobat, Conkeldurr, Stoutland. Not pretty. Not pretty at all. Not to mention either that a lot of the Pokemon are actually just cheap knock offs of Generation 1 pokemon (Woobat:Zubat, Blitzle

onyta, Timburr: Machop, Tympole

oliwag, Sandile: Sandshrew, to name a few).
I love Pokemon...Generation 5 is stupid.
