Well, it's not like F4F stuff is bad. I have three Metroid pieces from them (Varia Suit, both gunships), and they are legitimately fantastic.
I'm not sure they bank on character nostalgia or recognition more than anyone else, considering the general quality of the output?
The Awful Zero Suit face notwithstanding, Link's face is fine in all four incarnations, and there's nothing wrong with Ryo's either.
Can't defend the Zero Suit AT ALL, it's legit terrible, but it's like...one bad piece out of several good ones; I see no reason to write them off immediately.
