Glad to see that there's a semi-consistent storyline developing. I don't mind monster of the day for the first 1-3 episodes, but I prefer having a connected plot. It's a fun show overall, though I still consider it something of a guilty pleasure.

We're just now getting on the Supernatural bandwagon (only on season one) and honestly the shows are about equal so far. Contrivances and inconsistencies are major problems for both shows, but I think Grimm's cheese factor is -slightly- higher.
