First, I very much like the concept of emergency service personnel (our day-to-day heroes) although injured in the line of duty, able to return to work, albeit obviously changed human beings. JR Martinez brings his personal horror story of injury & facial derangement to his role & I sympathized greatly with not only his pain, but his social discomfort & sadness. Dolph...well...is Dolph. ...great in the typical quasi-militaristic plot but a tad sketchy in those little personal drama scenes. Texas Battle is good & believable, as is Karl Thaning. The plots have evolved nicely. (Among others, I enjoyed the container that submerged containing trafficked humans, and their rescue.). I would like to see improvement in the female role though. Why are their shoulders/arms so pitiful? Come on Lydia, Jocelyn & Katie, pick up some weights. Carry a hose pack. Work out for gods' sakes. This is not 1990 you know. I also liked Danielle Caley Anderson's playing of Kacie. She brought some fresh drama to the role of a non- emergency person/fairly abandoned kid's confused life. Inter-agency cooperation is tricky in real life with egos on the line & in the end, real life at stake. The season's second half showed much improvement in all ways and I'm looking forward to more rescue stories next year!
