Bertrand Tavernier's grim, melancholy film l.627 acts as an antidote to all those movies that show police work as an exciting fantasy. Here, in the Paris-set story of renegade undercover cop Lulu (Didier Bezace), it is mired in bureaucracy and petty competition among colleagues even the drug busts are anticlimactic. Tavernier demythologizes cops the same way that John le Carre does spies. Sadly, though, the film lacks drama: Viewers might begin to feel they are on a stakeout for 145 minutes. C+
