I tend to post to #db while watching shows, especially if folks there have already seen the episodes or will see them soon. I try to avoid comments that are too spoilery, so what I have to say is generally pretty shallow and unspecific, but hopefully my reaction to the final development will be apparent from the comments below! Here's what I wrote about last night's "Dollhouse":
<Wes> I can totally see Glau's booty through her skirt
<Wes> aaaand all is forgotten with the return of AA
<Wes> Journeybro!
<Wes> nooooez
<Wes> I'd wish I had more time with that loveliness too
<Wes> time for blue hair dye jobs
<Wes> wait what the fuck
<Wes> FOUR KNOCKS
<Wes> THE END OF THE DOCTOR
<Wes> ...
<Wes> what
<Wes> fuck this show
The usual suspects are already raving about how awesome the episode was, but I thought it was bloody stupid. Yeah, there were a couple of revelations -- one in particular -- that were "shocking" and unexpected, but it was in that comic-esque "ONO my new wife is actually my dead twin sister's baby from the future" way. Apparently the next episode or so will attempt to convince us that this twist was really in the works all along, but there really was no reason to suspect it -- unless one was simply expecting the least likely result to obtain for no apparent reason. I hate shit like that.
It's in these instances that the writing disparities between inferior shows like "Dollhouse" and "Heroes" (and "Smallville") and superior shows like "Dexter" are most apparent. The former shows drop these WTF moments on you without any warning, almost such that it seems like even the writers didn't decide to go that route until fairly recently in the story. With "Dexter," there are certainly WTF moments -- but they've not only clearly been carefully plotted beforehand, but also set up to the extent that the viewer has probably interpreted at least some of the clues correctly.
A good show gradually lays down the puzzle pieces in order to build towards the greater picture, though it might drop two or six pieces on you in rapid succession at key moments. Shows like "Dollhouse" meander along and then throw technicolor posters in your face while screaming, "BLAMMO!! YOU WEREN'T EXPECTING THAT, WERE YOU?!?!?"
And no, I wasn't expecting that -- but it's still bloody stupid.
