I actually don't care much for the characters but watch for the content instead. I like the various cases and scientific evidence...these sort of help keep the drama interesting.
yeah... well i guess. and the appearence of the characters make you addicted to the film, but so does the storyline.
After episode 18, I think the forensic part is still not that great but the stories and plots is coming together very nicely and I'm enjoying that part a lot more.
