Criminal Minds

I like Criminal Minds.  It is entertaining.  There is only one thing, it is totally unrealistic. So much so that it makes me laugh sometimes.  I realize that sometimes the stories are based on other serial killers, but serial killers are very rare, not to mention another person doing the same weird thing.  Plus once a week is a little much.  When was the last time you heard about a serial killer period?  BTK, maybe?  Before that Dahmer?  That was 15+ years ago.  So every time they work on a case they should look older, that would be realistic.
