Mediocre, predictable big budget "Alien" rip-off with BAD science

Rating: 4/10 (1 January 2019)

First, some Hollywood prostituting over China. Crew member thanks for their contributions (to building the International Space Station) Russia, American and China? China has not contributed any of the $180 billion or so the ISS has cost because they aren't on it. The science it the movie was ridiculous. He changed the atmosphere from Mars to pre-human Earth and he "lessened" the oxygen? This IS almost NO oxygen on Mars!! There was a lot on the pre-human Earth.
Meanwhile, against ANY logical quarantine procedure, the "scientist" lets the life-form crawl on his hand!! WTH?! In real-life, they sterilize spacecraft sent to Mars just to avoid the rare chance a microbe might survive on it coming from Earth.
Everything they did was wrong. They should have jettisoned Reynolds into space the moment the thing killed him. The Russian should have cut herself off during the spacewalk the moment the creature had her. Sacrificing themselves would be written into the rules of the mission in real-life in a situation like that.
Apart from the lousy plotting, the actions of the crew and dialog were trite. Blubbering like children over the death of a crew member when it was so telegraphed by the plot only an idiot would have been surprised.
This was corny. The kind of corny you used to see in cheap 1950's scifis where guy with a Brooklyn accent would be strapped with a handgun while exploring the moon and tossing off wisecracks about baseball teams.
The depressing thing about much of the scifi in Hollywood is the bad science behind it. There is so much great, interesting science, speculative or otherwise, I don't know why it's so hard for them to incorporate it into movies.
