I dont know why some people are complaining about this episode.I think it was brilliant with just the right amount of insight into the teams personal life. That last scene was LOVE! Small insights into the personal lives of the team members is always so interesting. They didnt over do it at all.
Coming to the case... The unsub was quite believable and especially his MO of using sulphuric acid to burn out the sense was quite interesting. And i think its pretty stupid if people are complaining about it being graphical: Helloo criminal minds deals with serial killers..the graphic part will obviously come in. And the best was that unlike season 6 there was actual profiling with the team discussing the why, how and what. I SO missed the profiling aspect last season.
Some may say Reid's behavior was questionable and Morgan suddenly forgiving emily seems out of place..But the thing to notice is that Reid is the youngest team member and in the past hehasshown to not handle pain well, his emotional outburst was perfectly justified and especially with JJ since he has always been closest her, Morgan on the other hand know how to handle himself and his emotions.
Awesome episode. Can't wait for the next one to come.
