i remember seeing this film....
I'll never forget George Kennedy's reaction when he comes home to find out his entire family have been murdered. I saw this film at a relative's house when i was about eight years old. I remember two other moments from this film.
1. George Kennedy swinging a guy around with a chain tied around the thug's neck.
2. The shootout climax at the supermarket.
This should stir the blood the same way Death Wish did.
