I caught up with Grimm On Demand this weekend and it's really great!!! The time slot makes me mad though - Apparently the 9pm Friday slot is The Time Slot for Sci Fi/Horror - Supernatural, Fringe and Grimm all air at the same time.
I'm still watching Terra Nova too as well as Person of Interest.
I just saw ads for a new show starting in January - Alcatraz. Haven't heard anything about it but it's got Sam Neill which is enough to pique my interest.
