The Killers deal in universals in a mawkish attempt to connect to everyone. If you continually speak in universals without attempting to to fully interact with them then you cannot fully appreciate them. The words in themselves become meaningless, a mantra without depth or context. Universals in themselves explain nothing, but must be explicated and disseminated in order to provide meaning.
By abandoning the story based songs of their previous albums and dealing purely in universals and attempting to appeal to the Everyman they only succeed in alienating those who were drawn in initially by songs such as the 'Murder Trilogy' ("Midnight Show", "Jenny Was A Friend Of Mine" and "Leave The Bourbon On The Shelf") or "Mr Brightside".
In terms of the actual tune itself, it is passable synth pop that references so many 80s artists it would be laborious to list them. It sounds dangerously like a retread of "Read My Mind" from Sam's Town, which was a lovely Springsteen meets Erasure impression. Perhaps coming from Las Vegas explains the ersatz nature of the Killers' art. Semantics aside, "Human" is a less than edifying experience.
