Haven't seen it, but I can say from a marketing standpoint (which is part of the decision to buy a ticket in the first place), it does look overdone (like someone said, "CGI'd to death"). I remember when I first saw "The Matrix," and although everyone else seemed to gawk over the "special effects," I instead thought of how they took me out of the story. They were overdone. "Special effects" should enhance the believability of the story, and never should they overcome the story. The same is true of costuming and other visuals. That is what seems to happen to all of these CGI-heavy and overwrought "live-action" stories these days. Again, haven't seen this yet, but the trailers head strongly that direction and leave me cold -- unlike the story itself.
As for Disney live-action itself, they have had some successes in recent years, but they are generally the ones that are more low-key and ones that simply let the story -- and heart -- drive the film (just like Walt himself so strongly insisted was the formula so many years ago -- not that they had to be low-key but that they had to have heart and a strong story). One that comes to mind is "McFarland, USA." That was a fantastic movie.
And as for adapting other material all the time in their animated classics, don't forget that "The Lion King" was an original story, as was "Brother Bear" (which was better than people give it credit for).
But overall, I just wish that they would realize that CGI, costuming, and "special effects" are like salt: a little bit goes a long way to enhance the product, but too much ruins the product.
