What starts off as a very run of the mill action thriller, becomes quite an original blood thirsty horror. Kirk Douglas is in fine form, portraying humour (see the scene with grannie in the appartment), grit, emotion, and pure anger. If only the rest of the cast (inc Andrew Stevens and Carrie Snodgress) showed the same passion.
Well worth watching, very unique, and grabs your attention within the first two minutes. Might not be the best film ever made, but at 5/6 pounds, well worth buying, as it will give you 2 hours of edge of your seat thrills. Forget his son, give the true Mr Douglas a go.
