The grass starter has those dull half-open eyes. The different-colour eyelid thing is horrible as well, I've been seeing it more and more on Pokémon and it has to stop, it's not because the technology finally allows us to add more colour to a Pokémon that we need to add as many as possible (also looking at you, firepigthing).
My criticism isn't that they're unoriginal, it's that they're badly designed. Rhyhorn, for example, is by far one of the least original Pokémon, but it looks good, it follows a logical pattern with its evolution, it's straightforward, and it's just a kick-donkey Pokémon. What made gen1 good wasn't its originality (lol, not at all), its the design and the flow.
I'll take a gen3 Pokémon as another example, Carvanha. It has 3 completely different colours all thrown onto one Pokémon, this weird symbol on its stomach (a trend which started with gen2, looking at the Ursaring-line (although I guess Weezing sorta qualifies as well)), bizarrely placed teeth and shares very little in common with its evolution (to the point where it loses a fin on its head and even a tail). Even very different Gen1 evolution-lines (Spearow-Fearow) at least follow a similar basic colour scheme and are at least easily connected beyond the fact that they both belong to the same phylum.
Sure, Carvanha is original, never seen a mouth like that before, a star on a fish?, etc. But that doesn't make it a good design.
I understand that some people might like the newer style, but in my opinion it deviates too much from the original style and therefore makes all the new Pokémon seem less and less like Pokémon. The original style worked well enough anyway (I mean, Pokémon became pretty popular, didn't it?), I don't see why we suddenly needed to change.
