Would probably appeal to fans of his 60's work
Of Godard's work from the last 30 years, Detective is probably the film that would most appeal to the people who like his 60's work, such as Bande à part or Alphaville, but find his more recent films to be too disengaging. Although Detective is characteristic of his work from the 1980's, in terms of style and approach, it also has the frivolous, anarchic, self-referential quality of something like Made in U.S.A or the aforementioned Bande à part.
It seems a bit unfortunate that this film, and several other Godard pictures from the same period, have hardly any discussion about them on the IMDb.
