Reminiscent of an older favourite dealing with a similar premise (I won't name to keep this potentially spoiler-free), this movie both gripped my attention and let me down at the same time. Good, solid performances, dependable cinematography, clever writing, interesting twists and turns and then, right there, in the middle of what could potentially make for a well-polished, wondrous outcome... the serum scene. I won't go into details but that plot hole was so humongous it almost caused me actual, physical pain.
Still, have my three stars, Mr Sodebergh. Just for making a movie that made me tolerate Channing Tatum, you've earned that much.
