The trailer of the movie really does a disservice to the work done. It's a slow journey, focussed on merely two characters. I didn't hate it, but I also didn't love it. Some parts dragged and I found myself looking for my phone, but I still watched it to the end, which was sort of poetic. Once again be warned, IO isn't an action thriller if you are wanting a lot of runs, trying to escape Earth this ain't that movie. If you're looking for a reflection of what we are doing to our planet, this may be an enjoyable watch. For you to judge.
