I totally agree with you in regards to the frustration of not getting the Colossus com face the way we all know and love him, trust me on that cause a part of me did hurt inside when I saw it. Now I'm assuming you didn't buy the statue, so let me ask you just from pictures you've seen is there anything else about the statue that really is off putting to you? If there is then I'm in no way recommending that you or anyone else that feels that way buy it. But if it is why would you want to keep such an amazing statue (excluding the head sculpts) from your collection? It def is frustrating that they chose to go this route on this com because we probably won't see another on of him in a while. Again though from my perspective the ONLY part of this piece that I personally would change is he head sculpt and if I have the means to do so, then why wouldn't I pick him up and just customize it myself.
As for the fixing these expensive statues, I agree this shouldn't be an acceptable norm...but if you love a character and most of a statue why not take the creativity into your own hands and make it what you want. Case in point how SSC chooses to release com's in regards to style and versions can be questionable at times and if a particular production run doesn't do anything for you then simply don't buy it. But if it does then why not grab it and if you think it could be better tweek it. Either way SSC gets it all right sometimes and sometimes not...when they don't as fans we can express our dislike of what was done but to state they don't care about what we want I think is more of an emotional reaction to what they tried to do. Last note there is nothing wrong with any editions of this piece staying in their warehouse if there aren't any interested parties and no one is claiming everything SSC makes needs to be bought. Buy what you like and don't what you don't.
