I can agree that Gen V had some weak designs, but really, every generation has its weak spots. I mean, some of Gen I's designs included a half-dozen eggs with eyes, an upside-down Pokeball with eyes, a pile of sludge with eyes and a purple rat. For every good design, there were at least two bad ones. It's simply the nature of the game; when you base Pokemon designs on common objects and animals, you're bound to end up with a few duds before long.
The games themselves are only improving, each generation having improved and built upon the generation that came before it. Really, the series has limitless potential, and there's nowhere to go from here but up.
