What would you want? That would make sense and actually work in an episodic format. We're talking about two brothers who hunt and kill evil spirits and the like, what could they really do with that?
I would want some connections between episodes, not just schtick! The first two episodes had this. Dad disappeared, while "hunting", the kids go to find him, find the journal, instead, and move on to the location that it points to... but now it's a dead-end! What I want are goals, always being worked towards. Right now, that's finding Dad, and filling him in on what happened to Jess, and seeing what gaps he can fill in. After that, it's finding "The Thing", and figuring out what hurts it!
Along the way, there can be occasional episodes where the (shall we say) "Meta-Plots" don't get advanced, but MOST episodes should relate to the resolution of one or two of these MPs, with occasional episodes that have NO FREAKS, but only advance the Meta-Plots. That gives three basic styles of plot, instead of just one!
1) Kids follow clues to next freak-encounter. They kill the freak, and gain a clue.
2) Kids are doing something else, stumble onto a freak, and slay it. Then they go about their normal lives. No new clues, this week!
3) Kids follow clues, either on Dad or Burning Women, encounter no freaks, but gain some piece(s) of valuable info, which helps them in future episodes.
There! THAT'S what I want!
We;ve got the Motive, Opportunity is easy, now all we need is the Means...
If The Steverooo had written the first couple of episodes, for instance, the first thing that Dean would have done, after getting Sam out of the burning house, would be to sit down and go through Dad's journal, looking for what he was working on, when he LEFT the White Woman. In the last episode, after killing the Wendigo, the cabe would have been carefully searched... They know Dad was coming here, so what happened to him? Did he get et, or what?!?
What leads them to the next episode? I hope they'll tell us, next week, but I doubt it... and even if they do, I suspect that it'll be something stupid like: "Oh, look, I just found a clue in this journal (that I've had for days and days)!"

Shucks, you'd think they would have looked there, first!
So how is the next episode connected? Oh, it's not?
YAWN!
And while we're at it, here are a few more plots for the Meta-Plotted show:
4) A "Day In The Life" show, where the kids are just shown getting along with the problems of daily life. No freaks, no clues, just paying for broken-down auto repairs, getting food, travelling, getting pulled over by cops, and explaining all that odd hardware in the trunk... Now is also a great time for character development. Which kid steals the car parts, and which washes the dishes to pay for the food? (Dean/Sam, is my bet!)
5) A Non-Freak Freak Show: They go in, looking for MP clues, and hear about a missing kid, think it's an "X" Freak, go in to kill it, and discover (Gasp!) that it's a lost-kid-down-the-well, kidnapping, parental abduction, etc.
6) A Day In The Life, pursuing clues. How do they get their information?
7) Encounters with other "Hunters": What? You thought these three were the only ones?
8) Cries For Help!: Someone comes to them, looking for help with a problem... This works best if it's an Anima Sola, or the "Strange Man" who was watching Sam, in Episode 1. That way, instead of "Just another Freak-of-the-Week", it can actually advance the Meta-Plot, as well.
9) Build The Network!: People encountered previously (like the girl and her little brother, from the previous episode, and/or a cop who searches their trunk, or even the black cop from Episode 1) are used to help out, gain information, or whatever. These people already know what's out there... Some of these can be "Cries For Help!", too!
Y'see, a Meta-Plotted show is much better than "Route 666; Two brothers drive across the nation, slaying bad-things wherever they meet!"
