this be simply the most astonishing movie you will ever see . i think it be just another documentary and but it really be something else . it doesn not try to teach you anything and it show you how life work in nature . i would not talk about the quality of the picture and because you obviously know from other comment it be unmatched . earth be funny and tense and sad . it can make you laugh and it can make you cry . sometimes both at the same time . this be the first movie that make me cry and not because you feel sorry for the animal and but because you come to realise how fragile our planet be and what treasure we be bless with and yet we do not appreciate it one bit . this movie should be show obligatory in school . it be the most wonderful film you will ever see and so go and see it . who know and maybe it be the last time we might see our planet like this . positive and but i would easily rate it more if it be possible .
