Actually, I'd rather they did away with the monster of the week episodes. Those were fine, and enjoyable. And you can have some underlying story arcs/themes with that format, some 3-4 episode larger arcs if you want, and be effective.
But IMO, once you take it down Grand Story Arc LN, the random episode with no baring on the current story line being thrown in is just annoying. "Hey Lucifer is still roaming the earth bringing down this whole apocalypse thing...but what the hell let's do something random!" No, I want to see what happens next damnit!
I keep waiting for the story arc to return to Dean's pendant/necklace that Cas borrowed once, back in season 4 or 5. It burns hot in the presence of God, or something like that. Can be used to track down God.
You don't throw something like that out there and then ignore it for 4 seasons. Especially with Heaven, Hell and Purgatory all malfunctioning.
The monster-of-the-week episodes irk me at this point. Seasons 7 and 8 had way too much MotW stuff and not enough meat to the plot.
I've seen WH13 and Torchwood...are there more episodes for these shows than the episodes on Netflix?
Being Human is okay... but I have a core complaint with a lot of these shows:
Vampires are EVIL. Not cinammon-sparkly-good-guys-that-brood, okay for tweens to drool over. I think Whedon started all that garbage (which is one of the only complaints I have about BtVS, and the main reason I don't like Angel). It's a huge reason why I like Supernatural. The lead characters hate that tweeny garbage.
Keep my vamps evil (or at least a dark secret society, like Underworld), the irony on full throttle, the RPM's at the red line and the mags topped off. And put it on TV.
