It’s just that, as a listener, it's easy to get the feeling that any other version of this band -- happy Interpol, smarmy Interpol, pissed-off Interpol, the tense-and-edgy Interpol of their debut -- would be more entertaining to listen to than the tapped-out, unsure act that shows up here, sounding like people who have come to loathe certain motions but can't stop going through them.
