While I can see your points I don't really agree in total.
QC, can it be an issue, yeah, is it all the time? No. Generally speaking this is about perception. If you ordered The MOS PF, Apocalypse, and.. we'll say Red Sonja, even though I think she's stunning, you'd say, "My god, Sideshow can't ship a single piece right." But in Contrast, if you ordered Harley Quinn, Superman, Red Skull, Punisher and Hell boy, you'd swear up and down that they nail everything. I think that people, especially on this forum tend to forget just how many products this company makes, and also just how many they get right. I also think that people, again, this forum in particular, think that they are owed something beyond a full refund. If something is wrong with a product, returning for your money back is a common enough practice and is considered, "making it right", but in collectibles, the need to have an item tends to drown out the fact that you can get your money back.
As far as ES is concerned, sure that works if you want the regular edition of the statue, but if you want the exclusive, you could well be out of luck by the time it ships.
I'll get to XM in a bit.
The base of statue should fit the character that sits on it. That's what I want. It's what Sideshow is foing with their DC license and Horror license. I don't know why the Marvel license is different. As for scale in lines, I agree, get out the measuring tape and make it right.
I agree on the Jean Grey PF and I honestly don't know what they were thinking. Had I seen that come out of the Prototype shop looking like that I'd have scrapped it and started over.
As for your comments about XM, and this "hobby"(I hate that word to describe collecting). It's true, this isn't cheap to do, many things aren't. But I see no reason to further inflate the prices of these pieces than they already are. Spending more just to get what should be done right the first time or for an extra switch out that literally at the end of production run probably adds and extra $5 in cost to the company to me is ridiculous. I already fork over a few grand a year so I don't need to go doubling the amount just because someone has a few shiney baubles they've added on and packed it in a different styrofoam.
XM needs to show me better sculpts, I know, I know, you guys like them, I don't, Before I plung money down, and to be honest it's going to have to be one hell of piece for me to spend more than what I do on Life Size busts to get my money.
