That is kind of like saying that Ang Lee's Incredible Hulk film sucking isn't a legitimate complaint about the film, and that you feel sorry for them if it ruined the enjoyment of the film for them.

By those standards, there is no such thing as a legitimate complaint, ever, and everything is awesome.

I doubt Warbler and I are the only ones who were thrown off by the films silly little in your face "easter egg", it clearly muddled things. Perhaps only for a very stupid portion of the population who have never clearly been able to get a grasp on the proper way of movie watching, but it is still a large enough number for that joke to have been a legitimately godawful, absolutely stupid idea of a joke. I fail to see how that makes it an illegitimate complaint.
