Grissom
On my favorite show the character of Gil Grissom is being written out of the show. I do not know if the show can go on with out him, he is such a critical part of the make up of the show. When he took a few shows off to do some theater this last season it was a down swing at least for me. I will not be happy when he leaves and will wait to see if the producers make the show better with out Grissom or if the show just fades away like most do when the star leaves.
