Chief of Station is your by the numbers spy/action thriller, sandwiched between cheesy slices of US exceptionalism.
There's nothing new, whatsoever, on offer here. This is a flick driven by exposition, with action that lacks a certain polish but is still superficially watchable.
Acting is alright too, just don't expect any Oscars to be handed out.
In summary, a basic formulaic US spy thriller that's mildly diverting and little else. Possibly a good one for a slow Sunday.
