I'm a MAJOR fan of the original tales the Grimm brothers compiled, and indeed have studied them and written a thesis paper about them. I would eat, sleep, and breathe the tales if I could.

Still, I'm decidedly a fan of Grimm. Like you said, they're getting into some of the lesser-knowns, and have a solid story line. I'm ok with the not so special effects, and the acting works alright. I think it will get better as it goes along and they get used to their characters and explore motivations a bit more. At least, I hope it does. I'm crossing my fingers for more than one season, but also counting my blessings that it got picked up for the full season!
