Personally I think too many people get caught up in appearances. This is true in the real world as well. There is not a single design flaw that I can see in any of the Pokemon we've seen so far. Not one. Nit-picking one feature or another when we know next to nothing about the Pokemon themselves is really quite off-puting. I tell you, I would rather have the most disgusting-looking Pokemon if it also proved to be the most valuable Pokemon on my team.
