Very confusing plot, but somehow still somewhat entertaining...

Rating: 7/10 (21 June 2011)

I have read quite a few books about the events detailed in this movie. Even with this encyclopedic information at hand, I still found the movie very very confusing and I think it was because they tried to make it an amalgam of all the Infernal Affairs movies and also incorporate the real stories into one coherent story.
The one big noticeable thing that the movie does not cover is how the BPD probably had the most moles working for all the different factions. Since a lot of the BPD are drawn from all the different neighborhoods in Boston, the complexities of their various clan and ethnic loyalties probably deserve a movie of their own.
The acting was pretty good, but I have definitely seen better performances from all the principals in other movies. With a plot so byzantine, their heads must have been spinning trying to keep things straight!
