I enjoyed this movie greatly. Although the plot has been somewhat rehashed many times the performances here stir emotion. Especially Liam Neeson's. If not for his performance in this movie I probably would have given it 4 stars, but he shines brightly here. The loyalty and love of his character combined with the contempt and anger of his character, what a great performance.
When this movie first came out I didn't even know it. I don't know how it fell off the radar screen before ever being noticed but it is cerainly worth a look.
Buy it - enjoy it, over and over.
