I just watched this movie and i thought it was horrible..

I gave it a 4/10 and im a generous person..

Im trying to figure out what i missed, maybe it does more for the americans watching this movie, maybe i didnt understand the history and all those things, but for me it was a waste of 2½ hours(its very long).

Have you seen it and did you like it?, What did i miss so badly so i thought it was a bad movie, because it was been given amazing reviews in almost every magazine and programs.
