Grange Hill was a kids drama set in a school. It followed the lives of a few groups of people and a few individuals as they learn things and generally grow up.
Personally, I have loads of fond memories from Grange Hill. I think the Zammo on drugs storyline was great. I think Jackie, Zammos girlfriend, was WELL fit. I thought Rowley was a fat nerd. I disliked Rowleys girl friend (2 words, not 1) simply because she called him "Row-Laand". I think Bronson losing his wig was ACE! I think Danny was a depressive and I shuddered loads when there was a dead body in the pool.
Quality kids entertainment.
