10 Worst Horror Movie Decisions With Unbelievable Consequences

10. Investigating The Suspiciously Perfect Planet - Alien: Covenant

Let Alien: Covenant serve as a reminder of one elemental fact: if something looks too good to be true, it almost certainly is.

At the start of the movie, the colonisation ship Covenant is seven years away from the habitable planet Origae-6, with 2,000 colonists and 1,140 human embryos in tow.

But plans change when the crew picks up the sound of a human voice from a nearby planet, which appears to have almost suspiciously superior conditions for life compared to Origae-6.

And despite the protests of terraforming chief Daniels (Katherine Waterston), Captain Oram (Billy Crudup) makes the executive decision to change course and land on this planet instead.

Yet Oram could've never expected the catastrophic knock-on effect this choice would have.

The bulk of the crew, including Oram and his wife, are soon enough killed by alien organisms on the planet, before the two "survivors" - Daniels and Tennessee (Danny McBride) - accidentally grant control of the Covenant to malevolent android David (Michael Fassbender).

Given that the final thing we see in the movie is David placing two Facehugger embryos in cold storage among the human embryos, while Daniels and Tennessee are both helpless in stasis, there's absolutely nobody to challenge David as he continues his deeply screwed-up experiments.

So congratulations, Oram: your eagerness to cut corners got your entire crew killed and probably doomed a couple of thousand colonists, too, not to mention anyone else who might find themselves in David's firing line.
