Yeah, I've only seen the TFA Chewy in a LCS a few times, but it really was staggering just how bad the face looked in person. The ANH face most definitely has its problems too, but its like a 7.5/10 for me, while the TFA is like a 4/10. I really thought when Solo (where Chewy's almost a main character) was upcoming HT would surely give us the "definitive" 1/6 Chewy, but alas - nope.
I actually recently bought a THIRD ANH Chewy - only because it was $140 shipped (I've actually never paid more than $220 shipped for any of my Chewies - not sure how I did that) - and the face actually looks a bit better than my first two. I do seem to recall some being better than others, but I noticed it as soon as I took it out. Nothing massive, but it just somehow looks more screen accurate, less beak-like.
I now have on display a "3PO backpack" Chewy for my ESB display, a Chewy standing next to smuggler Han for SW, and this new one I've redone the forehead hair to look ROTJ style and put a chain/loop on him for Jabba's palace ROTJ Chewy next to Bousshh. All OT Chewies now taken care of.
Now I just need to finally get around to redoing/modding the faces - something I've planned but put off ever since I got my first one. Except now I have THREE to do.
