Someone on a YT review pointed this out in the comments.
1. There is a ship full off over 2000 sleeping passengers. Yet they have one, just one android to look after it all. Why not have 3, 10 or even 20 androids! They don't age, and surely should one fail, you need a backup! Piloting an entire ship usually takes more than one person!
2. A rogue solar flare hits the ship disabling it. It goes unexplained. Combine that with the random stray video signal, and M-class planet that appears out of nowhere, you scream "It's a trap!" If anything, it would appear some sort of attack.
3. An astronaut outside the ship picks up a stray signal through his helmets two-way radio, that somehow appears in visual form on the glass of his helmet? Yet the giant ship with the radio dish right next to him misses it!
4. That stray signal apparently happens to be a song in English. Yet who transmitted it? How did you determine the artist from the white noise? What they found on the planet later no-way explains why they sent a song into space for no apparent reason!
5. They are able to trace a stray video signal to a planet two weeks away at star-ship speed. Where do I begin to show how stupid this is?
6. They don't want to go back to sleep, so they go off exploring. Fine, but then you don't need to send almost the ENTIRE crew down to an alien planet! A scout team of four would have sufficed. Or maybe just the android on recognizance.
7. They pilot the drop ship through a plasma storm, yet it is sunlight clear within seeing distance. Why not fly around the storm?
8. Its clear intelligent alien life was on this planet. It sent radio signals out, there are buildings everywhere and a city, even a spacecraft. All of which could have been scouted from the ship while it flew around first. Scouting your environment first is rule 1 in any explorers handbook.
9. They land in the water, even though solid ground is just ten metres away. The water of an alien planet with unknown worms, piranhas and other possible alien lifeforms in it. Unstable ground is not wise to land on, and then to get your shoes wet why?
10. And they open the bay door while still trying to land, not after. Surely you open the door after landing, not during.
11. They open the doors without testing to see if the air was breathable. They don't bother wearing space suits, they don't send the android out first to test the area, they don't even bother to take down one of the truck that they clearly have at the end of the film.
12. They leave just one person on the ship, and leave the bay door wide open in unfamiliar terrain.
13. There is human vegetation (wheat) on the planet. Why? Did they just take seeds with them for the fun of it? What was the point of it?
14. The guy goes for a smoke when he is on protection duty of an alien planet. Astronauts are unlikely to be smoking, cigarettes are unlikely to still exist and he is unlikely to have carried them on this mission. But they do say "smoking kills"…
15. You do not let an infected person with an alien disease back on your ship. He should have been left outside.
16. Don't open the door to a quarantine lab with a monster in it, and don't go inside and slip on the blood.
17. When you miss the alien and shoot the wall of your shuttle with metal bullets, they usually ricochet and bounce around since the wall is metal, designed for interplanetary travel. The fuel canisters are not usually left inside the ship, on the wall next to the door.
18. Why was there a Quarantine bay on a shuttle?
19. When following an android on an alien planet with a flare gun, through a dead city full of dead bodies, don't bother asking him about any of it. Or suspect him as the only survivor to have been the cause. And don't show any emotion whatsoever of walking through a mass graveyard.
20. Androids kissing each other. Android David raping a woman. Why?
