Yep, I must admit I had to watch it a few times to see it was bad CGI. Someone screwed up big time on letting that one slip. Sound issues are even more noteworthy and incompetent. But you really have to be looking out for it to take you out of what you are watching. I thank my failing health that my eyesight isn't what it should be so overall I really don't care if a dodgy scene is present - diabetes for ya.
The more honest discussion should be about the good and bad of the overall product was, the lack of, or gained enjoyment of the special; people are just overtly critical these days and one sided about these first world problems around entertainment. Lets move on as Spiderman the movie is next.
