I'm not sure you people were paying attention. Did you just erase all the times Hope stepped up when everyone else was on the verge of giving up from your memories?
As for blaming Snow, maybe he just has trouble accepting the fact that his mother was responsible for her own death? I doubt any 14 year old would have an easy time dealing with that but hey, go ahead and begrudge him the entire day or so it takes him to come to terms with massive emotional trauma if you must
I don't know what people are expecting, unless they want a young teenager who sees his government betray him and his mother
die to shrug and say "Meh, whatev". Also everyone is overlooking that every single other character deals with all sorts of




. Lightning is so unable to deal with life that she sets up all those walls, can barely have a relationship with her own sister, and hides behind what is effectively a screename. Snow hides his massive weaknesses and failings behind his douchey "herp derp im a hero" attitude and it takes Hope calling him out for Snow to stop acting like a retard and admit that he's not a perfect hero. I doubt that anyone would cut Hope a break if he put a gun to his head, but Sazh? Haven't seen anyone call HIM whiny yet. (And before anyone says it, if losing your son is a fine reason for that sort of thing, so is losing your mother.)
If you folks honestly think that Hope was at all "whiny" then I guess there's no convicing you otherwise, but I don't see it. At all.
