"Book 'em, Danno."

It's been seven years since we started to hear that phrase again. Before 2010, it had been 30 years. Still it persisted in the modern lexicon along with the term Five-0, which is still shouted in high-crime areas in cities all over the country whenever a police presence is felt closing in on the bad guys. Hawaii Five-0 ended in 1980. That's when Tom Selleck took over the sets and production crew on Hawaii to work as Magnum P.I. until 1988 when it all closed down for good -- or did it? Wouldn't you know it, the show has been resurrected and become the hottest drama on television. A younger Steve McGarrett and company are back in action and Hawaii ...the world might never be the same again. Not sure what I'm talking about? You've got six seasons of the new Hawaii Five-O to catch up on. Let's give you the quick 411. Roll wave... Click Here.

The 12th season of Criminal Minds would be one of great change. Some were expected and some were not. There had been incidents behind the scenes that had drawn red flags among the cast. Thomas Gibson was known to have a temper and had been reprimanded for it in the past. But as the Season 12 shooting began, he crossed the line again by allegedly kicking a writer. It was the last straw, and he was quickly fired from the series. So while the season begins with his character, it only lasts a short time. This is also the first season without Shemar Moore as Derek. That exit was planned and dealt with at the end of the previous season. And while everyone else returned, there was an unexpected return to the cast. Paget Brewster returned as Prentiss in what was originally intended as a short run. The sudden loss of Gibson created an opportunity to promote the character into his spot. Of course Brewster isn't the first to leave and return later. Jennifer Jareau had left for a while and returned to the fold. And while Moore does make a cameo this season and could return, don't expect to see Thomas Gibson on the show again.

As some doors close, others open. Adam Rodriquez from CSI: Miami joins the cast as Agent Luke Alves.  The character comes over from a fugitive task force and has a bit more of an aggressive style than the team is used to. He's a loner who lives alone with his dog. So we also get a rather pretty dark German shepherd in a recurring role this season. His addition certainly shakes things up in the character front. Another new face is Damon Gupton, who plays Agent Stephen Walker. He's the direct opposite of Luke. Stephen has a wife and kids and winds down by playing the trombone. To say he jazzes up the cast would be an understatement. But how well do these new characters fit in?
