Muk/Grimer aren't? They're basically the same thing as Trubbish/Garbordor so by that logic, they've been out of ideas since Gen I. (there's a lot of plain/basic Pokemon in Gen 1 too like Magnemite's line. which are just magnets. ) Plus I don't think they're really out of ideas since there's thousands of thing yet to be made into Pokemon.
Bisharp/Pawniard look similar to Japanese bandit who wear samurai armor. Which explains the humanoid like appearance. (They're not the only humanoid Pokemon you know. I.E. Jynx and Mr.Mime. )
Though I guess it's your opinion *shrug*
I already stated mine, I don't like Tentacool and Zubat cause how much they appear in water/land.

For me, it's Mewtwo. I don't like legendaries a lot, yet Mewtwo is by far the worst.
It was too powerful in Gen 1 (the reason competitives had to create the Uber tier in first place).
It also received too much unneeded drama during the first movie. Really, the first movie was what made me to hate it so much in the first place. I can't feel any sympathy for it, I am sorry...
And it's now going to appear again, in M16! NOOOOOOOOOOOOO!
