You could build a suspension bridge over the gap between what "Robin Hood" could have been and what it is. Its hero is credible as a man who wants to rob from the rich and give to the poor, but the storytelling is so impoverished that the message can't stick. 
Robin Hood" is a malleable tale, but the core is always the same: a cocky underdog fights the power on behalf of mistreated citizens. This new version from director Otto Bathurst ("Peaky Blinders") captures the heart of the legend, but frustratingly fails to translate it. Bluntly political and surprisingly coherent in its messaging, the movie is filled with deliberately modern details signaling that it's a folktale aimed at modern multiplex audiences, closer to a science fiction or fantasy epic than a "Barry Lyndon"-style "accurate" representation of life in another era. If the filmmaking and writing weren't so undistinguished, this could have been special. Instead, it's a flat and often grating experience, dotted by pockets of intelligence and surprise.
