I watched the 3-part crossover - Chicago Fire to SVU to Chicago PD. Overall I enjoyed it, although there were some plot holes you could drive a truck through (for example, Chicago doesn't have their own version of SVU?).
I reconfirmed the fact that Chicago Fire does nothing for me. It appears to be a soap opera with a fire thrown in now and then. SVU is still a very good show. Chicago PD is okay but does not keep me interested enough to DVR.
That being said, the topic was disturbing and the outrage that both police departments displayed was right on. Well worth the time.
