A stain on Alien's legacy.

Rating: 5/10 (26 January 2018)

Where to start?
Let's make a few educated assumptions first;
A. We can all agree that the Covenant crew were highly educated, intelligent individuals since they carried responsibility for over two thousand colonists.
B. The colonists' survival was paramount and would have been the number one priority throughout their whole endeavour.
C. Walter, was a physically improved version of David
Now that we've established this, quite a few scenario's stop making sense.
SPOILERS AHEAD
The crew's stupidity
When the Covenant's crew discover this new planet and decide to check it out, they exit their ships without any protective gear; no helmets, not protective suits, nothing. Even if the atmospheric scans didn't show any signs of imminent danger, does this seem like a decision highly intelligent people in charge of a human colony would make? To stroll out of their ship, onto a new world with an unknown ecosystem without any precautions? It doesn't, does it?
Once having egressed their vehicle, the planet quickly showed signs of past life; the wheat at first and the massive structure a bit later. How come the lack of any discernible living organism never rang a bell? Wouldn't that simple fact put anyone remotely sane on high alert? What about the hundreds of humanoids that were obviously victims of a disaster?
Then, of course, we have the idiot that isolated himself to take two puffs of a cigarette; just enough to get infected by the spores and go back to the biologist taking samples. One could argue he took some distance in order not to compromise the scene, but it wouldn't be a solid argument.
Then we have Oram, arguably the most stupid individual ever written by anyone. When he finds David standing in front of the Alien that had just brutally decapitated a crew member and asks him to move, he refused. Not only did David bask in awe at the sight of the beast that had already viciously murdered more than one crew mate, he also cried in agony when Oram unloaded his rifle on it.
A sane person would've shot David through the head after that. Not Oram, no. Apparently his stupidity had not reached the intended climax yet, for he lowered his gun and promptly followed David when he asked him to join him in his creepy cellar. Upon entering this cave like space Oram was confronted with the classic face-hugger eggs. With visible disgust in his eyes his approach was careful, until David told him it was "perfectly safe" of course.
Sure, trust a synthetic that had nearly lost his mind when you killed an unknown organism that had devoured your crew member. Why not?
He closed in on an egg and when it opened he practically stuck his face in it.
The perfect organism
The first question that popped into mind when seeing the classic eggs was: "Why do these even exist?" Wasn't David trying to perfect the Alien life form? Why then did his genetic modifications complicate the insemination and gestation? If you remember, two crew members were infected by spores secreted by small, nigh invisible egg-shaped organisms or fungi not long after having touched down on the planet. Doesn't this seem a much more efficient way of inseminating human organisms, rather than having large, obviously disquieting eggs produce an organism that must impregnate you orally? It doesn't make any sense.
As a long-time fan of the Alien series, I feel this film should be disregarded as a whole. The horrible writing and worse directing makes it frustrating to watch.
Films and stories in general, needn't be realistic. But they do need to respect the reality they're set in.
Ridley Scott should take the back seat; even David Fincher was able to create a more believable universe with the highly underrated Alien 3.
What a damn shame.
