the story of the movie be not really to bad and something like that could possibly happen now or in the future . some part of the story be really kinda silly and do not make much since . the story do not flow as good a it could have . the acting be another really big part that keep the movie from be good than it be . some of the actor action be just not really believable and do some very odd thing . this be another big factor that keep the flow of the movie from be as smooth a it could . like i say the storyline be for the most part believable and but their be some hole in the story . their be a lot of part where they do not go into enough detail so you really do not know whats go on . but overall i give contagion a rating of 4 .
