Very disappointing

Rating: 2/10 (21 May 2017)

Before I start, I really must stress this includes spoilers.
I'm beginning to doubt Ridley Scott. This movie, as far as the characters go was basically a b-movie teen horror flick. People wander off by themselves, no normal or expected precautions are taken and we even have the obligatory sex scene killing.
The ship takes a detour from their colonization mission to check out an unexplored world. Nevermind they've done extensive research on their intended destination and none on this new one, they go straight down to the planet without EV suits or any real intelligence gathering from space. There are no precautions taken for diseases, microbes etc which you'd expect to be taken by a group of astronauts and which the original Alien crew took. Characters wander off by themselves to "take a leak" and predictably are infected. Even after they have sick crew members, does anybody put on a mask? Hell no. The one sop to rational and standard medical precautions (quarantine) is rendered meaningless because the person instituting them has already taken a spray of blood to the face. If it was a disease, the rest of the ship and their cargo of 2000 colonists are all infected. These actions go contrary to current medical practices, never mind those less than a hundred years from now.
A ship carrying 2000 colonists and isn't capable of landing on a planet only carries 1 passenger shuttle and a cargo shuttle? Do they plan on making 100 trips to the surface when they get to their colonization destination? It's manufactured drama.
A synthetic they know from reports by the manufacturer is dangerous is welcomed with open arms. No precautions are taken.I guess if you're not going to be worried about diseases why worry about a known serial killer?
Every single character acts less like a professional and more like a 16 year old on a camping trip. Emotions control all their actions, but not in a believable way. The crew doesn't want to go back into stasis after a catastrophe kills some of the crew and 47 colonists (they even seem to forget about the dead colonists after that initial report going with "2000" anytime it comes up later). Instead, they decide to go to an unexplored but closer planet. If they were so concerned with safety wouldn't they take at least minor precautions with their new destination? If they were actual astronauts concerned with power, food and water supplies wouldn't they continue to their well-scouted original destination? Send out a satellite or two? We have drones now, wouldn't they have some equivalent 80-90 years from now? Wouldn't they take some time exploring the planet and its ecosystem before jetting down in the only passenger shuttle they have? Even the final twist is telegraphed well before it happens.There are no real surprises and I felt like I was watching Troll 2 in space. Ridley Scott has made some really good films but this one is a stinker. Bladerunner is one of my favorite movies and I won't be looking forward to Bladerunner 2049. He still doesn't accept the inner monologue of Deckard is what makes the original so special, turning science fiction into a film noir masterpiece like The Maltese Falcon. If this Alien movie is a sign of what to expect, I'll stay at home.
