Is a dark, dark, darkly funny, violent, absurd cop-tale that about 15,000 people in America will want to see. I'm one of them. (Ironically, Stephen King is probably another.)
The first 40 minutes or so are like watching a pretty good British TV show; the next hour is like a twisty American thriller; and the final 10 minutes are a mess.
Through it all, Mel Gibson is a movie-star.
If indeed, the end of days is approaching, then apocalyptic flicks like this one are making our remaining time pass rather tediously. Legion would have been an okay pilot for a show on the FX.
