I understand your point, but as much as I try I just don't see it that way.Every one of your examples show the character (the main point of a statue) having a very different pose. The Big Chap recast however is quite literally the SAME statue, SAME paint, only a different base. Like everyone said, if the Big Chap was a different sculpt this wouldn't be so much an issue. So no, your comparison does not fall under the same category.
If after I receive my 1:3 Predator they recast one with a simple base, I don't think I'd care because the base is part of the appeal to me. The reason I didn't like the OG alien WAS the base/wall. So, I like the new release much better.
I'd honestly prefer a 1:3 City Hunter with a simplistic base. I'm not fond of the ship.
