Spoilers: high (for nerds, anyway; for non-nerds who can already guess what could go wrong with an action movie smooshed into a preexisting intellectual property, moderate)
Written by Richard Maibaum, Johanna Harwood, and Berkeley Mather (based on the novel by Ian Fleming)
Spoilers: severe
Note: runs a bit longer than I'd have preferred, mostly thanks to the inefficiencies of getting a retrospective of a film series of this magnitude started
