Most of them are ugly, hands down. I thought that (and, always have ever since Ruby and Sapphire) the new evolutions were a let down (save a few here and there; of course this is always a matter of opinion).

It looks like somebody did it in MSPaint with a blindfold, saying 'Oh, whatever happens, happens, and we'll call it a day!' *furiously scribbles lines with the mouse while bopping keyboard with a rubber hammer*
