As a long-term fan and player of many video-games, I think that I can clearly say how good or bad PC graphics today exactly is, of course even the games are not about graphics at all, players always wanted the best visual experience, heart-breaking, photo-realistic quality and stuff like that, everyone want that. . and yet, still in the end, it's the gameplay that convince the player to play it or invest the time on it. Movies have totally different problems than games, in games. . every little thing is created by the computer graphics, because that is the only way how to create something in a virtual reality. Believe me, there is not much players that actualy rather prefer movie cinematic sequences in games instead of classic computer generated animations. It's reasonable. . if you want to play a game, I guess you should as a player got a game with full cgi animations and everything, but of course. . some of us could like the movie sequences rather than actual cgi ones, there are even these people. On the other hand, movies trying to do they job differently, actors and directors are trying to act as best as they can, so they can convince us about their roles in the story. What Im trying to say there is, movies are made in reality. . if the directors choose to made things in their movies realistically by using prosthetics, costumes and real mechanical toys, man. . it's their way how they try to convince us, and we should be glad for it. . because our eyes (or atleast my eyes) always recognize what is real or what is not real in the screen itself. So, if they try made the things without using the PC's, they made it practical. . and that is always in any way more believable than anything ever produced by the computer graphics. . the problem with computer effects is that most of the time they look too perfect, and that is not believable at all. Why it is like that? It's simple. . computer is trying to define or show something that is hard or near impossible to do in reality, the result is (in this case) almost perfect looking Alien doing perfect movement in the perfect ideal timing, with the perfect camera position, you know what I'm trying to say there? It is everythihg too perfect, and that is the reason why it is miles away from to be even real! I don't think that we see all the Aliens in the entire movie only like this, of course not. . dear god I hope for more prosthetics. But still, If there is a some good mix with both cgi and real costumes in this movie like they say. . it is clearly evident that it's not the case of this specific clip. I think that overall image quality of this clip is bad enough, so it can hurts the computer effects even more. Watching anything in lower quality made it worst, if you like movie and got the Blue-Ray version of it. . than you can judge.
