You probably know this feeling when you see poster of a film or even a title and think - it sounds or looks silly, they must be kidding, I won't see it. And then after some time you read a positive reviews one after another, some of your friends told you that the movie was awesome and the imdb shows you something above 7 in rating for this movie.
At this kind of moment you think - wtf? They must be trolling, how can it be true? And during these thoughts you are opening site for rent/download this film.
This exactly the situation with this film - "Rise of the Guardians". When I've read description I remember I thought its another silly movie for kids. But when I finally started watching it quite quickly become obvious that this animation film is really worth watching it. Animation is great and the nature of the characters are fully disclosed and voiced by good actors.
I know it would sound weird and maybe can be hard to believe in, but this movie has soul, you certainly feel that people, who've done it really worked hard and it was very enjoyable to watch it.
Again this would can sound weird, but after this movie you feel this warm feeling inside you and life seems better.
So, as the moral of the story I would try to be less judgmental based only on small amount of information or on first impression. This can stop me from watching really great movies.
