A couple of years ago I was really into script writing and, through some family connections, I was able to get some of the blacklist scripts to look at before they went public. Passengers was one of them and it was a really good script - it was sort of unlike anything I'd read, and figured it was going to make a tremendous movie. When production began and they cast Pratt and Lawrence, I was a bit confused, they didn't seem right for the roles but I also knew they were hot stars so figured they were probably capitalising on that. The director, Morten Tyldum, was coming off the acclaimed "Imitation Game" and felt he might very well be an excellent choice.
Then the trailer hit and you could see it was just seeping with mismanagement and confused marketing - they were definitely trying to put all their eggs in one basket instead of sticking to the vision of the script, which was much more about human nature then we got in the end.
So we get a weird movie where you sort of sympathise with Pratts character but equally dont , and it's a real uncomfortable cognitive dissonance - then the third act happens which is choc full of deus ex machina with an ending that doesnt really feel that natural.
It would have been a much better film if they hadn't tried to make it a big budget block-buster - it's a film about two people; it doesn't need a $120 million budget.
Edited to add: This is the type of film that could have easily been a cult favourite alongside something like Eternal Sunshine of the Spotless Mind with a really novel approach to relationships and the expectations we have of people; instead, they added 80 million to the budget and made a mediocre sci-fi film.
