The Brink of Law

Just finished The Brink of Law...I'll have to admit, we were slightly disappointed with the ending because Ron died...Come on, he was stabbed by this old guy with a knife. Didn't he see it coming? I thought he was stabbed in the stomach but he was stabbed in the heart. Also, why did he stay to listen to the old man anyway? He had the chance to run away after pushing michelle away. In our view, Shirley should have been killed at that scene. Ron would have escaped and called the cops, then the bad couple would be put into custody and Michelle would heartfully ask Ron to look after his brother. I thought that too many people died in this series that were not anticipated and not necessary...such as Ron and the other cop (played by Kenneth) much like the death of Raymond was a mistake in Hearts of Greed...I would give this series a 3.75/5...I think that it is worth watching, but nothing too spectacular about it...How did you about the ending? How would you rate the series?
