For me, this a rather unique show in that all main characters need each other for the show to work. Angela needs Hodgins as a foil, and Bones sure needs Booth. There is no replacing any of these 4 actors - as far as I'm concerned.
By the way, the actress who playes Cam is one of the most exotically beautiful women on TV!!!
Damn he is hot, and a great actor, nothing then when he wore his COCKY belt buckle, OMG, he is sex, seriously, and can act oh yeah, I enjoy his work, would like to see him in another TV series can never get enough and the seasons are shorterand far apart on all the shows, wt heck
