What Pokemon types do you think are done well thematically, and which ones aren't? That is

Water I would say does it well. Electric is weak thematically because so many are just "yellow elemental animal that shoots electricity and is pure Electric". Fighting, Rock, and Psychic also fall in similar boats in that they typically don't do much with their type's theme. A lot of fighting Pokemon are just "it's strong". A lot of psychic Pokemon are just "it's smart". A lot of rock Pokemon are just "it's a rock". Like there are tons of rocks in the world, make Pokemon based off of those instead of generic pebbles and shit.
