I don't like paradox cop outs for endings

Rating: 5/10 (21 January 2017)

The movie is great at keeping your attention to the screen but that doesn't make this a great movie. There's just too many plot drivers which run on "for the sake of it".
Yes OK she is learning their language and so unlocks the ability to access the past, present and future memories at will but hang on an entire team of people are deciphering and learning that language too. I'll have to watch the movie again but doesn't she start having the visions with very little understanding of the language?
I just generally have an issue with paradoxes when they are used to end a movie which is on a difficult position of resolving the issue they currently face.
In arrival the future chat with General Shang is on the basis of her having already made the call and told him his wife's dying words. Time being non linear or not you cannot gain information that you have 0 access to so that you can give that information conveniently to yourself.
The daughter. This is such a sensitive topic but ultimately one thing I am certain of is that she has no right of withholding her knowledge about their, not hers only, their daughter from Ian. Plus it looks like knowing fully how he will react when she, and I'm assuming this is why they are apart, tells him about the disease after the daughter is born she is probably going to do that anyway too.
Overall this movie is not smart it is just great at keeping a mystery not worth knowing.
