Not a good thriller film

Watched a film yesterday named 'The day of the jackal' and as a thriller it was one of those you'd only ever watch if you had to. To begin with the film moved quite swiftly moving from the back ground of a faction and an assassination attempt, from then on it became bland, boring and too slow, after half an hour of relentless torture at the hand of the director i turned the film off. It just came to a halt and lost all of my interest.
