This thriller/comedy never reaches great heights but is solidly entertaining throughout and that is more of an achievement then one might give it credit for. To be sure, the plot elements and romantic element of two people who can't stand each other for most of the film but eventually fall in love has been done a million times before in various films over the years.
But usually, films containing these elements come across as hackneyed, tiresome and dreary in some shape or form but Blindfold never feels like that and is consistently good fun throughout its journey. Credit for that must go to Hudson and Cardinale who work well as a team and Hudson is especially effective in the film's more comic moments. Jack Warden is reliably effective in his supporting role.
While Blindfold is no classic on any level the solid entertainment it provides is something Hollywood consistently struggles to achieve to this day in films created for that purpose.
If you want to see a really bad example of this genre, see the abysmal pseudo-hip caper comedy A Fine Pair starring Hudson and Cardinale again which is a disaster on all levels.
