I agree completely. It would be much more interesting if the insignificant characters were in the background of the episode. For example, i like who they got to play the blind witch, but in some ways i would almost have rather them keep the other blind witch. That was one thing that was interesting about LOST. In the first episode you don’t think anything of Locke sitting on the ground and then they show him running around, but then when you go back and watch you realize you can see Locke in the background of the episode even before you knew his story. That is interesting.
