There are some awesome pokes. The problem is there is only 70 something pokemon and the amount of crap is higher than the amount of omg awesome imo. That being said, I wouldn't peg it as the worst. It is def up there in crap gens though, but like I said, mostly because there are so few good pokemon in it.
The only new ones that I don't like the design of are the legendary Y-shaped bird thing, the psychic cat thing and Avalugg. A handful of uninteresting ones out of seventy or so new designs isn't too bad. Diggersby made me laugh out loud when my Bunnelby evolved. Trailer trash rabbits with beer bellies and ear fists are the best HM slaves ever. :-)
Some of the sprites are clearly rushed though ... the elemental monkeys for instance had a nice See No Evil, Hear No Evil, Speak No Evil theme in the Black&White games, but now their overall theme seems to be "stand still and look generic" instead.
