Well, first you have to demonstrate the bodies were real bodies, and not SPFX props. Simply saying that they
looked real isn't even legitimate grounds for suspicion, much less substantiating evidence.
As to the reviewer's AHA status, read what he actually says in his review. It's %100 blind speculation: he doesn't cite any evidence other than the images he saw in the final film. He doesn't even cite any circumstantial evidence. He doesn't cite or even imply any special knowledge or insight from the AHA. His only stated grounds for excitement are that the images looked real... to him (this is important: some people have a better eye for this than others). His entire shtick is trying to parley an open-ended unknown into a positive suspicion. His reasoning stands alone, and can be examined alone.
http://en.wikipedia.org/wiki/Appeal_to_authorityHe might be right, it's not like I actually have any more hard evidence than he does

. However I would say that for most of his suspicions it is circumstantially
extremely unlikely, and he really should be aware of this if he's anything close to knowledgeable enough about film production to justify his job. Furthermore, at least one of his suspicions is physically impossible without special effects, and two others can't be considered legitimate issues without extending similar complaints against any film that happens to show non-vegan food at any point, or even includes it anywhere in the craft services menu.
At the very least, the
DVD releases of the film have multiple commentary tracks, making-of features, and other such materials likely capable of answering many of those questions, one way or the other.
I'm not trying to argue for or against any given position, mind you, I'm just weird in that I'm usually way more offended by illogical argument than I am by actual issues

. His suspicions have no logical or empirical basis: If he's right about any of it, it's purely by blind luck, and he tries to use emotional appeal to reverse the burden of proof (successfully, it seems: he's got nothing, but he still managed to put you in "guilty until proven innocent" mode). That's what bugs me.
