I did for the most part enjoy the episode and the chain reaction of the hacking was an interesting concept. However, I did believe that it lacked one or two things which could have made it amazing.
A lot of time was dedicated to the hacker girl, and I have to agree with thefanof because she was not really likeable at all. Shouldn't she be charged or something? Her actions led to lives being lost...
The other thing I didn't like was the classroom scene. That could have been one of the greatest moments but there were far too many awkward silences and that scene seemed half-hearted, although I did love Kensi's reaction and just walking away at the beginning.
The case was good without being great. Not the best week of NCISLA but still a worthwhile watch if you ask me.
