Just saw Hell or High Water, written by Siccario's screenwriter, Taylor Sheridan, and starring Jeff Bridges, Chris Pine, and Ben Foster. The easiest way to describe it is as a bank heist movie, though it really has more in common with Westerns (the story is set in present-day west Texas but it could just as easily be set in 1880 or 1930) and 1970s road movies.
It's a very solid movie, with a nice caper plot, a solid cast, and good motivations for its characters. It's very easy to give a thumbs up to, especially as I wandered into it on a lazy Sunday with essentially zero expectations.
While it's very solid, it's not a modern classic or anything. The plot and setting mean it will invariably draw comparison to both Siccario and another movie about a west Texas lawman who ponders his own mortality while tracking down stolen money, No Country For Old Men.
Nothing quite stands out enough to put it in that exalted league, though. Jeff Bridges has fun chewing the scenery, but we've seen this kind of character go through this kind of plot plenty of times. Ben Foster is perhaps the standout, but when all is said and done it turns out he underplays his role pretty drastically. The biggest issue is the pacing, which is expansive (or, if you prefer, slow) in the way that early 70s movies were. The problem is that where early 70s movies would fill in all that extra space with character detail, Hell or High Water just fills it in with ... not much. So it seems merely slow, a criticism I also had with parts of another 70s-inspired flick, Midnight Special.
Still, like Midnight Special, it's the kind of movie that, when you stumble across it on Netflix or cable, you say, "Hey, that was pretty darn good. Why didn't I hear more about it when it came out?"
