I gave it a 7.5 out of 10

A movie that not only functions as a solid scarefest but a razor-sharp satire.

This is a small, humorous movie in some ways, but it has a huge heart. What a nice experience.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

This film is really bad even for 80s Belmondo standards. Story? None. Belmondo is looking for his friends' killer and chases cars, beats up and kills people in the process. At one stage or other the director seemed to have noticed that this wouldn't fill 90 minutes and added the character of a child. So all in all it seems like a tough and nasty version of a 60s Eddie Constantine film. It is interesting though that if you watch the film closely you'll notice that props and cast also feature in some other 80s Belmondo movies. The overall impression is that nothing really seems to fit story wise as well. The whole film seems to be made up of odds and ends. In Germany the film was called The Professional 2- a bit pointless given the fact that the original professional actually dies in the first part.

Jacques Deray,who recently died, made several commendable works ,even if he never made a masterpiece:"la piscine" "un papillon sur l'épaule" or in his latter days "un crime".But "le solitaire" has nothing going for it:here Deray is Belmondo's drudge,trying to direct a star who overplays and who single-handedly gets rid of the villains and even the treacherous cops.They added a child's character (Belmondo's godson whom he takes in after his father's death )to sweeten the violence ;the brat is subject to some gaffes concerning Godfather's love affairs.This is supposed to provide the poor screenplay with a comic relief.The film wasn't even a commercial success in France which had begun to have enough of these cops and robbers flicks

this is one of the very best of belmondo! see, how the "old bebel" is hunting for the killer of his cop-partner. one of my favourites... i am looking for all belmondo movies. since early 50s he was getting more marvelous and a "strong hero". belmondo is the greatest actor in europe!
