Ignore the overly biased reviews, this is what it is:

Rating: 7/10 (22 December 2016)

CGI - 8.5/10. Acting - 7/10. Script - 6.5/10.
No Spoilers.
Well first things first, the trailer revealed far too much and was a total misrepresentation of the films pace - the action sequences are confined to the last 35 or so minutes, but this isn't a bad thing at ALL. The previous hour and 10 mins is exploration of the situation our characters find themselves in, the human condition, and decent character development. I'd describe this film as a romance action drama with undertones of suspense, set in space.
CGI -- The amount of money spent on the CGI almost tricks you into thinking that you're watching an action movie from start to finish, it's incredibly well done! Polished and presented beautifully, with enough detail to transport you right onto the star-ship, and keep you there. Some great external shots with two particularly awe-inspiring moments.
ACTING -- The acting was good throughout. I say 7/10 because I know that both actors are capable of more (aimed toward Chris Pratt more than Jennifer Lawrence). Whilst the script also held them back somewhat, there was still room for them both to shine at different points - two very specific scenes stand out, rising above the clichés that we're normally fed. But unfortunately, there were also clichés...
THE SCRIPT -- It ALMOST escapes that intellectually removed dark void of Hollywood influence, and is indeed buried nicely under pretty pictures, pretty actors and pretty action, but it does drip through in a few places. So we get an occasionally cheesy romance drama in space, rather than anything *truly* deep and meaningful, like Interstellar gave us. The redemption to this is an intriguing moral dilemma that most of the good scenes are attributed with, and the first 20 mins of the film which I can't describe without spoilers.
KNOW WHAT YOU'RE WATCHING -- It's definitely not as terrible as some reviewers are implying, you just need to understand what you're going to be watching (which, again, was misrepresented by the trailer and likely the cause for most poor reviews). It IS good for what it is. It succeeds at making you question a thing or two, laugh a few times and has enjoyable characters, but not a huge amount more. Also, it may be set in space but seen through the eyes of a true Sci-Fi aficionado, absoluteellyyyy nothing of significant grandiosity occurs. The trade off is that a Sci-Fi fan will still enjoy this film for it's CGI and futuristic setting, but it's also open for the typical girlfriend-boyfriend movie night.
CONCLUSION THEN... -- Overall, Passengers works, doing almost everything it seemed to try and do. You should see it at the cinema if you have the chance. The CGI alone make it worth it - the ship was like an extra character in the film, somewhat literally! Just try and understand what this film is first.
