I love Woody Harrelson. But seriously, this script? Trite, predictable, humourless. And proof that it's not what you know, it's who you know. And you really know a film's bad when in the final dramatic moments, when life or death is in the balance, you just couldn't be less interested in which character lives or dies. My kids enjoyed it, so there's that. And based on that, it was £16 (Sky download) well spent, because it wasn't £32 spent at the cinema.
