This show started out great, balancing personal and medical themes. But lately it's become a circus full of ridiculous writing, inconsistent character developments, unremarkable and unconvincing dialogue and delivery, and an unbelievable power given to the main villain.
The writers and producers of this show does the audience a disservice. They're not telling a compelling story anymore; clearly they're making this up as they go.
We don't need anymore characters to get the plot going; we need justice to start prevailing instead of the opposite.
