Since 'Zack' left,the show started getting into personal lives of the characters & distracting from the point of the show. I adore Booth & Brennan,as well as Angela & Hodges, but so many unnecessary characters have been introduced to replace'Zack' that the show has been bent out of shape. WHERE IS 'ZACK' &why can't we bring him back? Hell,why not create another show-a spin-off,if you will-where he gets to do his special thing??
