The thing is though... it happens every time (except at the beginning obviously) with every bunch of starters revealed, every set of cover-legends, every secret event legend, with new waves of mega evolutions etc.
I'm always flabbergasted when reading posts like those, because they either have no actual argument besides the assertion itself (which often happens to draw a line between whatever generation that person lost excitement in Pokémon at, ala "gen x were still cool, then it went downhill"), or the arguments are extremely flawed.
|Yes it is literally trash, but it is also the cutest|
and most thought through well balanced
living trash-monster design ever.
Being a generation 5 Pokémon (a generation meant to show that Gamefreak can make fresh unique interesting designs even if they are direct homages to older pokémon, proving that even if they ever "ran out of ideas", that wouldn't stop them from making more Pokémon, but that's another of these topics), the hypocrisy is easy to point out however: one just has to realize Grimer is a thing, yet no one ever complained about it in that manner.
If pokémon only included generic animals with an element slapped on them, Or if they were only insects... or only dragon-like creatures, or only humanoid designs, only plants, only spirits etc. it would lose one of it's main aspects.
Instead the inspirations for the designs come from everywhere, with the result being that everyone finds some they like.
It's one of the aspects that give Pokémon so many levels of diversity.
I would argue that the designs usually picked on tend to be ones that are actually one of the more original and creative of them.
Pokémon would not be Pokémon without all the strange designs thrown into the mix.
Some fans like the cool badass dragon designs the most, some prefer the cute ones, some like ones because of particular themes, colors and details their designs combine, others like ones with darker or mysterious backstories... and some like the strange ones.
Personally, I embrace that whole spectrum and always find something likable about them and try to figure out what non-obvious interesting origin they might have.
So, keep expanding this colorful family Gamefreak :3
