It had plenty of cool ideas, just needed a smaller run-time
I think it's a pretty good movie... The twists were mind blowing in my opinion. I'm happy I saw this in the cinema.
I enjoyed the film, but I think it was mostly the performance of the actors that drew me into it. The plot was alright, the visuals were alright... but the performances were VERY good and turned an otherwise "casual" film into quite an enjoyable one. The best part of the film was pretty clearly any scene with a turret in it, though. The way they would glide ominously, the sounds--kudos to the designers, they did a great job making them imposing but totally believable as real technology.
