movie "alive"

I watched a movie "alive" first part of story was interested for me because i used to watch movie with gaurdian and housemates. then suddenly airplane was fall in the Andes Mts. somepeople was gone , died and hurted. finally they were deliveranced. when i watched this movie one part made me felt like vomit. because the ate human flesh. it was so disgusting. and i knew that they were really wanted to live even they had hardship and they never give up. if i had that situation i could not do that. so i thought they were so brave. now i`m respect them..
