By coincidence I caught this film the day when according to Harold Camping the world was supposed to end or something. And again coincidentally, a very strange weather was on that day, it was unusually dark for the morning hour I saw this, at one point it started to rain havily, and towards the end of the film the clouds started slowly making way for golden sun rays. Truly it was good atmosphere.
It didn't help it.
The problem with Legion isn't really its story. The concept of an Archangel opposing heavenly politics and opting to fight alongside humans against the impending apocalypse is a pretty good one. And Paul Bettany is very good in the role. Then why the hell do we get nearly 2 hours of people shooting at zombies with rifles? I have no idea whatsoever. The film picks up a bit towards the end when the Archangel finally gets into more divine stuff, but it's too late to save the rest of the film. The other characters are not developed enough, and clichés abound (all black characters and the spunky girl die, surprise!). In the end what could have been an interesting film is nothing but a mediocre 21st century actioner.
