Why so much hate?

Rating: 8/10 (15 May 2017)

I've seen "Alien: covenant" yesterday and I was blown out by this film, that reaches to my opinion the same epic greatness as "Prometheus", with which Ridley Scott completely reinvented the saga "Alien". I love the first films for their sense of terror and suspense. I loved Promotheus because the implications behind it gave me the vertigo. I think this was an attempt to give deeper and stronger implications to the saga, while keeping the bound to the early films, giving us explanations years after to the inherent questions that were raised back then.
-SPOILER ALERT- I read a lot of critics against the plot, especially the fact that the characters are not strong enough and do not always make totally rational decisions. Of course, they don't. Is this so surprising or disappointing? What would you expect of characters that are lost in space, have to confront incredible and unexpected hardships, and, on top of that, who just lost their main commander? What about the characters of the first "Alien" movies, were they so smart and intelligent, always a step ahead? Anyone who has seen them knows the answer. It doesn't make the story less interesting or more stupid, on the contrary, it's what makes it real. Characters capable of failure are mirrors of ourselves, hence they help us to really get into the movie. You want to see perfect characters, go see "Captain America" or the tasteless, dumb movies of this kind that poured out of the studios continuously for the past ten years or more.
Alien: Covenant is a sci-fi masterpiece that is actually a counter-attack against the lack of imagination of the big budget movies of these days. You have here an exceptionally well-written, terrifying, complex and visually stunning sci-fi movie, one of the best I've seen in many years.
I don't understand all the hate. I even read somewhere that the visual effects were not good. I feel sorry for the people who are not even able to wonder and be amazed by a movie like this... Just open yourself and don't listen to the haters. Go see this film, and enjoy it!
