Right?!? I was just happy to see Brent Spiner as Data again. It was around First Contact where he was publicly stating that his time as Data was coming to an end because of his age. If an imperfect wig or less impressive de-aging (compared to what we have gotten spoiled with in the MCU) is the price to pay, then so be it.
I was certainly happy to see Brent back again at all, however, they did initially convince him they could effectively de-age him, then when he's onset they call and tell him they can't afford to, he then tells them that he only needs to look like he did in Nemesis(which is totally correct) and in an Interview with Brent and Marina, she says he looked terrible in the first Trailer(Im assuming his screwed up hair) that Vinyard scene, his hairpiece was too far back and they digitally pulled it down(initially way to low in the teaser) then in the final scene between Data and Picard, the hairpiece they used was way to low, and digitally pulled up(in all fairness a more acceptable job in mot shots) It's a crap situation where it really felt like the Powers that be were trying to take the cheap way out every time, and didn't give a rats ass about things like Data's distinct hairline. although I enjoy it for what it is, it's not very comforting to know that the show is in the hands of people who would let things like the crappy hairpieces fly, there is no good excuse for why they should look like a hack job, other than serious lack of preparation and or care. now I don't take much issue with his uniform, but the zipper is damn distracting, and the fact that they did take the cheap way out with a not so accurate replica is just another example of how this whole thing was mistreated. that Uniform got the Job Done, the hairpiece is a mess, though it looks it's best in the final episode(with better attempt to digitally fix it) the first episode it was just ugly. back when Spiner was playing Data regularly, things like the hair were for the most part consistent, even as he aged and needed hairpieces, they at least had the right look, the bad hairpiece would not have gotten off easy back when Nemesis was made, because they couldn't digitally fix it. regardless of whatever the actual problem was, it still comes off as a "we'll just fix it in post" which is not impressive, and it's a mentality that's become far to prevalent in Modern Film making. I respect that people put Effort into the show, but I'm not going to be so grateful that Brent came back at all, that I will act like the hairpiece doesn't matter, it was a serious screw up, and Brent got the short end of the stick, and thats not comforting, Brent's not responsible for his hairpiece, so trashing the hairpiece is not trashing him, the people people who didn't insist on some standard perfection for that ugly thing are who I'm pointing at.
In terms of the deaging work on his face, it's a bit of a mixed bag, but most of it is very acceptable all things considered, they did give him a facelift, they removed his double chin(too much at times) they did a pretty good job of smoothing his face out yet retaining some skin detail, which is an effect I've experimented with for over a decade, and it's not a walk in the park when trying to make it hold up under scrutiny, so I applaud them that they did as good a job as they did with it. yes his face could have been slimmed a bit better than it was, but I can totally live with that, the Hair situation is the one that is an eyesore, now what's done is done, but that does not make it ok, it just means it is what it is.
in interviews Brent has eluded to being less than thrilled with the job that was done, but obviously he's professional enough to outright trash anyone.
Now those criticisms are the Make-up Artist/VFX Artist in me talking, with the perspective of always having to pay attention to such details.
as a Trek Fan, I'm very Happy with Data's Scenes and story inclusion, I was extremely pleased with his final conversation with Picard, It totally resonated for me, it was beautifully written, and beautifully performed, it had a good deal of heart.
