NCIS: Los Angeles
I was introduced to this by the same friend as NCIS. Of course it was inevitable really that I would follow on from NCIS with it sequel. At first I thought it cant possible be as good as the original. Luckily I was wrong. NCIS:LA manages to create a unique version if what is a hit show. It combines the same team mentality but with a completely new setting as well as its own approach. The team members once again each have their own unique dimensions. Some more complicated than other, but they all gel together perfectly.
