At the end of “Ronin” (1998), spy/hitman/something-or-other Jean Reno becomes narrator and utters, “no questions and no answers.” Well, I have questions and would like some answers. If anyone other than John Frankenheimer had directed, could a post-Cold War espionage flick starring Robert De Niro have possibly been as pointless and opaque? And what is Frankenheimer’s obsession with assassination attempts at big events? And how do you have a seemingly endless car chase through Paris and encounter only one cop? There’s willing suspension of disbelief and then there’s willful ignorance of reality. Is that what was in the secret case?
