If watching a season of Criminal Minds simply makes you just want to watch more, that is a sign of success. Season six is a strong one that focuses on the BAU team's secrets. Emily Prentiss (Paget Brewster) has a story arc that is the highlight and gives you some of her international-spy back story, as well as a new secret for J.J. (A.J. Cook) and Aaron Hotchner (Thomas Gibson) to share. Episodes that focus on Dr. Spencer Reid (Matthew Gray Gubler) are always the bright spot of Criminal Minds, and it's hard not to wish that his secret weren't explored more in depth, but perhaps the creators are leaving that arc for season seven. We also get the introduction of a new character, Ashley Seaver (Rachel Nichols), whose father just happens to be a serial killer. David Rossi (Joe Mantegna) is a bit in the background for season six, but maybe it's because he's been at the center of previous seasons. Shemar Moore's Derek Morgan is always nice to look at, but remains the least interesting character in the cast--even his "secret" isn't very compelling--though it is always good to see him interacting with Penelope Garcia (Kirsten Vangsness), who has an appropriately lighthearted secret of her own. Overall, this is a strong season--and even if you're not a longtime fan, it's an easy show to just jump into. Extras include deleted scenes and some fun behind-the-scenes looks at the Paget Brewster arc, the season as a whole, and how various crime scenes are created. You may think your next-door neighbor is a serial killer after watching a whole season, but that's just a delightful side effect of Criminal Minds. --Paige Newman
