First of all plot is good like all other alien movies sound affect in theater is awesome and you can feel the thrill and fear. Screen play is also very good. This time in movie they upgrade visual effects in movie. Music and sound play at background is awesome. Director did good job and also all all other members. Movie is all about acting and plot. I am sure Some of them will think plot is not realy good there is no turning point etc. But according to film this plot is best an can’t gey any better.
