yes the plot is implausible,and so politically incorrect that you can't believe.but the film does what it sets out to do-entertain.this is ground that has been covered before(Beverly Hills Cop as an example),but never in a way that is as much fun.the screenplay is o.k.,with the best dialogue reserved for Hines-Crystal banter.the other characters are basically filler.but generally well done(Joe Pantoliano as Snake is great).there are a few dead spots in the film,but these are usually rescued by Hines and/or Crystal,who seemed to be having a lot of fun.there is a fantastic chase scene late in the movie that alone makes it worth watching.altogether this '80's buddy movie still holds up.mostly because of the insanity of the two leads.
