Sorry Pentum but this is an excuse. Look I don't know the technology and I won't act like I know it. Every example we have seen - such as Tupac and Audrey Hepburn and even the Avatar movie (which was done by these guys as well) - required an actress/actor/body double/motion capture etc. So if that's what the technology (or time or money constraint) requires then people are being unreasonable in their approach and evaluation of this situation.
Also a little rational thought should tell everybody that even if there's a double, they won't obviously state that well because it's not good publicity. Would Dr. Dre who spent $1 Million out of his pocket for Tupac Hologram go on record and say "by the way that ain't tupac. we got an body double and a soundalike to fake it"? Why do you expect Estate or anyone else to come out and say "That ain't Michael"? Doesn't that defeat the purpose? The purpose is to create an illusion, make people feel like they are watching Tupac and/or Michael when they aren't actually watching them. So they really wouldn't out the illusion.
I'm sorry to say - and not limited to you personally - but sometimes MJ fans aren't strong in realistic approach to stuff. It's almost like they can't accept limitations, conditions and reality. Reading this thread at times it almost felt like some expected Michael to rise from his grave and record a motion capture of his dance. Come on people.
for the record : I'll agree that the face CGI isn't the best one and yes could have been improved. I'm not crazy about the dance either. visually - the background, dancers etc- I'll put it far far better than Tupac one. So my evaluation of this isn't positive. But if they needed a body double (whether the technology, time limitations or the cost required it), I won't go crazy about it. Because at the end it doesn't matter if they billed it as "Michael Jackson", I'm able to realize that ain't Michael Jackson and posthumous releases (regardless if it's an album, a video, or a hologram) cannot be "Michael Jackson" no matter who they bring in , what technology they use or how much money they spend on it. I personally do not need any source or official statement to tell me that. I know that, I shape my expectations around that. I don't expect posthumous albums to be at the same level as MJ's studio albums. I didn't expect this hologram to be exactly like Michael either.
