Finally..

Rating: 8/10 (16 June 2017)

..they've reached the dam..Airlock, everybody agree, the very first Alien was/is a masterpiece, nobody can do better except R.Scott.
So for me, Alien Covenant is as good as Prometheus is a disaster, Prometheus was beautiful, design wise and bad because of the weakest women lead in the franchise or the lack of a strong one, here it's more like the very 1st one.
We follow a colony ship -the Covenant- who must reach a new planet with 2000 people +crew and embryos to start over, they'll have to stop, because of an accident during a routine made by Walter (M.Fassbender)which lead to woke up the Crew earlier and then because they'll receive a com. from a smaller planet around, this time it's not Mother who stop the ship and it's the captain who order the discovery mission, (you know, between 7 yrs in Cryo sleep and a few weeks to reach a new heaven, it's easy to choose.)
Every thing will go wrong as soon as they arrive because, even after a century of space travel, they are not prepared to walk somewhere else than on the good old Earth. When they land it's Earth like, but there is nothing except forest, water, lakes and ..wheats, no birds ,bugs, or any single animals, just some form of pollen; Now take a women who is in charge of a shuttle but can't handle a sick person without a panic attack and it will opens hell's gate for the whole crew.
They'll be rescued by the only one person around, an hermit played by.. M.Fassbender-who is terrific here- (like in Prometheus BTW)and if you remember Prometheus, you'll know at first sight where they are.
the 1st good point is, even the cast isn't unknown, they are not that famous which is really good (for me) (i've seen alien the 8th passenger in theatre, i was young and i just know , T.Skerrit and J.Hurt by that time) they all did good, but a really special mark for Katherine Waterston, she don't have a cat, but what she surely have is, Rippley's spirit and.. balls.
the 2nd one, whether some people here like it or not, A.Covenant is the best sequel to the 1st one than any other, of course they'll do the same mistakes, of course you know what's gonna happen, but it's more dramatic, it's less claustrophobic (slightly),more fast paced.
Thirdly, R.Scott used a lot from the 1st and a few idea from the 2nd and the 3rd opus in this one.
Don't think i've spoiled many thing here, but you'll discover a bigger treat than the Xenomorph himself in this story.
I don't know if there will be a follow up but i hope so, for those who says R.Scott killed the franchise, they are really wrong.
i recommend this to anyone who like Aliens
