I'm not reading that review, mostly because it contains spoilers. Yes I have read the novels, but I'm desperately trying to forget it, because I want the visual impact to hit me full force instead of "Oh yeah that awesome scene is going to come next!"
Anyway, what I'm guessing is that the author of that negative review has not read the novel before, or mayhaps, any Haruhi anime for that matter. The problem is that The Disappearance is not a movie for the casual moviegoer: That guy with the Koizumi avatar (who people has resorted to calling Koizumi instead) has pointed out that the movie does not even try to establish who the characters are, instead jumping right into them getting comfortable in the clubroom.
So for people with previous Haruhi experience, the movie is going to be awesome!
