Whoever reviewed this film as a fantastic piece of cinema either didn't actually see the movie, or doesn't understand critical thinking. They might benefit from taking a film class. I'd be wary if you are reading five star reviews of this film when it is indeed one of most sloppily put together messes available on Netflix.
Yes, it has Ryan Reynolds. Congrats. You've got a guy who quips. Great guy, decent actor, not the right role. It's just Reynolds doing Reynolds things. In fact, none of the characters really make sense. Their motives aren't really explored, the villain has no legitimate claim to even be apart of the story, and the stakes aren't even worth explaining apparently, since there doesn't seem to be any. The whole idea is that the future sucks, but there's no evidence of that, and none of the movie takes place in the future spare a few minutes in the opening scene. There's no real development of anyone, and there's some pretty bad de-ageing of one of the characters that makes you cringe.
The movie's pace is definitely there to distract you from all the bogus science, silly dialogue, wierd chemistry between the actors, plot holes, and lack of fleshed out ideas. It's just a rollar coaster type of film made to distract you from anything real. If you want to waste 90 minutes with a dumb film, this is for you. In fact, this would probably be a great film to watch if you're planning on having sex halfway through it. It has some decent one liners, and some cool moments, but I can't imagine anyone who respects art to think this is a good movie. It's just a silly Ryan Reynolds film that's not even rated R.
If you choose to watch this, good luck.
