IA2 (a prequel to the original) was a lot more complex plot wise. it was cool to see many returning actors come back to play their role. this film focused mainly on Leung's character now played by a young Shawn Yue. This was a typical undercover cop type movie in my opinion. still enjoyable a definite must see if you watched the first IA.

Internal Affairs 2 gets a 7 out of 10.
