At the current moment, reports are showing that Alien Covenant is not going to cross the 40 million weekend hurdle and come in at around 36 million. That will place it 3rd after AvP. I think bad word of mouth is going to hurt its numbers at the box office.
3RD UPDATE, Saturday, 11:25 PM: Disney/Marvel’s Guardians Of The Galaxy Vol. 2 came back strong Saturday with an estimated $15.3 million, up 74% from Saturday, to a point where some analysts thought for a second it would overtake 20th Century Fox’s Alien: Covenant, which fell 21% from Friday with $12M today. Alien: Covenant is still on top for the weekend with an estimated $36.1M, but now it’s the third-highest debut in the series behind Prometheus ($51M ) and Alien Vs. Predator ($38.3M). GOTG2 is just under $35M in its third weekend, with a running ***e poised to be at $301.7M.
The CinemaScore breakdown for Covenant shows 69% males to 31% females, with no one giving the sequel any A scores (except for 7% who gave the pic an A- for Katherine Waterston’s performance). Fifty-nine percent bought tickets because it’s and Alien movie, and they gave it a B. Twenty-two percent came because of Ridley Scott, grading Covenant a B+.

Yup. Prometheus' trailers were way better too. (The visuals, the Alien "siren" audio track which is up there with the Rogue One teaser in my opinion, the way it was cut, what it did and didn't reveal, etc). Regardless of what one thinks of the final product those trailers got a lot of butts in seats and that's all that matters. Covenant didn't. The trailers gave away too much and for some that turned people off. I know for a fact that the last CGI shot of the Xeno headbutting the glass while facing a Comedic actor was enough to send a ton of fans into a panic, and not in a good way. Plus the fact that Prometheus was Ridley's actual first "Alien" movie since Alien (NOT Covenant) probably helped with getting butts in seats.
I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched Androids blow and finger each other's flutes.

Prometheus was a good film that would have been even better if they added half the cut scenes back in. What would have been nice is if they carried on with the story. However FOX wanted an alien/xenomorph.
Lets hope the next film gives the fans what we want.

exACTLY, Simon.

I agree with you guys. A direct sequel to Prometheus would have been great

Personally, Prometheus should have remained in its own universe separate from Alien.
Below is the current totals up to today. Another hundred million and it should be in the profit category but with overseas receipts, 20th Century Fox gets less.

Weekend box office review sums of the disappointment box office of Alien Covenant.
As social media monitor RelishMix noticed on the social buzz heading into the weekend, “For the casual moviegoer, there remains sincere confusion over where the series is at this stage. Viewers are wondering if this is a Prometheus sequel, a prequel or some offshoot within the series that has nothing to do with the original characters like Ripley. Others still were wondering if the film was related to Interstellar because of the similarities in the musical score. And, comments specific to the ‘Crossing’ short, directed by Ridley Scott, express more confusion. Will this be part of the DVD extras as a deleted scene? Is it important to see this before Covenant — or after?” Also, it didn’t help that during the early development of Alien: Covenant nee Alien: Paradise Lost, Scott was wishy-washy on whether the sequel would be the further adventures of Prometheus‘ Noomi Rapace character Elizabeth Shaw. Early on that was apparently the plan, then there were headlines that she dropped out of the production, followed by news that she was definitely aboard and shooting scenes. Well, Rapace isn’t in Alien: Covenant except for in photos.
Critics gave Alien: Covenant a similar Rotten Tomatoes score as Prometheus, that of 73% certified fresh, but CinemaScore indicated that fans weren’t wowed any more than they were with Prometheus giving the sequel the same B grade.
And that screams volumes here as to why there’s ennui with Alien: Covenant, especially from a fanboy POV. Scott has delivered nothing fresh or jarring in regards to Alien: Covenant and twin Michael Fassbender androids isn’t going to cut it. Once you watch Alien: Covenant, it’s largely a run-of-the-mill Alien chase movie like we saw during the 1980s and 1990s. CNN’s Brian Lowry was one of the few critics to actually call that out (“Ridley Scott — who birthed the original nearly 40 years ago as well as that last film — plunges back into the latter’s mythology, with equally uninspired and perhaps more blatantly derivative results.”).
