It's about getting what you paid for. I don't expect 100 accuracy with the prototype but for me personally they missed the mark to much..
Well seeing as it's not in hand, I don't know why you're being so over-dramatic, because you are going off of photos. People hate on photos, constantly, when things usually end coming in pretty close, once in hand. You mock the T800, but after I posted photos, those not drinking haterade, said it looked better than they thought it would. I really haven't read a post where someone who bought the T-800, said it was horrible, or sent it back.
Looking at the photos you attached, shows obvious light differences, so that leads one to believe it might be a light issue, not paint. Either way it looks fine to me.
You are cancelling before you have 100% reliable information.
