Okay, I was into it for the first hour, atmosphere, a bit of intrigue, effects, and Jim, but then it just took a turn which ultimately made the last 10-15 minutes a write-off and plunging what was a 6/10 until then into a 5/10. Shame, it was never great, but if the film had ended after an hour I think I would've felt less disappointed.

Anna Maxwell Martin, if you're wondering who Ellie actress looks the spit of, you're welcome!
