the first link included my opinion, lol
edit: films dont stay in theater for that long if they dont sell, so you got the "7 months of prime time theater" the other way around since it is not the reason why it sold, but rather the consequence of being popular :V
the trailer sucked, xD
there are other films with a good soundtrack that dont achieve the same level of success, mind you
Did Elsa become repaired completely once she sang Let it Go? Does suddenly the part where she breaks down again when Anna tells her that Arendelle is Frozen disappear and falls into despair?
Which flaws? Other than some animation mistakes, I dont see narrative flaws. I am not lowering my standards for kids movies, xD.
