Kind of interesting concept but no real new ideas. Characters aren't very well developed. Tau was half okay but there was no real emotional weight to the film. I could see where they were going but there was a lot of half cooked ideas around.
Perhaps if it wasn't so keen so show off some a "cool looking robot" design and swapped some of the actiony bits for more touching moments it could have been an interesting film. Bit too flashy, not a lot made sense, wouldn't really reccomend the film
