I saw it last week and really enjoyed it.

If one is an experienced quantum physicist or tends to think too deeply about "how did they do that?" there were some fair sized holes in the plot. But if you figure it's a sci-fi movie and just accept that somehow they solved the technical details then those holes don't get in the way of a good movie. And the whole premise of the "ghost" - either one likes those loop arounds or not. I thought it was pretty neat myself.

But mostly the movie is a good story about people and family and that's the basis for every good movie or book. They tied up all of the loose ends and didn't leave you hanging although they didn't try to bog you down in detail either.

And the photography was simply amazing, the space shots were as good as if not better than "Gravity".

Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!
