Rushed and unconvincing. Aside from the sci-fi spectacle, I didn't enjoy it.

Rating: 3/10 (22 July 2017)

I am guilty of watching something purely because it's sci-fi which was the case with this. If you're wondering if it's worth your time, it probably isn't.
Perhaps because it was trying to summarise a book there were leaps in plot that didn't make sense, and the characters felt very shallow - they started as stereotypes and stayed that way. There was never a satisfying explanation why a bunch of youths were treated as great military leaders. There seemed to be no reason for lead-psycho-kid to make his leap of understanding about the aliens. The film didn't take time to build a world that matters with a plot that goes straight into a sterile spaceship. I didn't care if they won or lost or how they went about it. The spectacle was OK, with good-enough looking shooty space-bits, but it wasn't enough.
