This episode had an energy to it that hasn't been around for a long time. With the story being anchored by Warrick Brown and his son, it just felt different. Brings back memories of when CSI use to be 'must-see TV'. It's also a reminder of how far off the cliff the series has gone since killing off Warrick [/b and the departure of Grissom, Sara (she left, but returned a year later) and Catherine. I miss those days and those characters in particular.
