It's been a while since I've seen eps with dead Davenport, but I'm remembering that his story resembles the Voudou mythology of the sorcerer reviving a corpse with its spirit remaining tied to the dead body.  Once reanimated, the zombie is under the sorcerer's control, its spirit imprisoned and its mind devoid of free will.

Did you know that Zombi is the name of a powerful voodoo snake god?

This is also the ep with the opening voiceover that was rarely seen in US syndication and never seen nor heard on the Sci Fi Channel, so original fans who wanted to see it again had to wait til MPI released it.

It's not a problem. 

Please don't ask me why, but during the first conversation in which "understand" was tossed back and forth, I started counting the number of times the word was used and got up to 9.  Apparently Gordon Russell's understanding (!) of why the Leviathan plot has started to crumble mostly has to do with whether or not the followers understand.

But he did write a passable internal dialogue for Barnabas:  "Everything is getting out of hand. I'm losing control. I must find a way out of this. But how? Why is it there are moments when I doubt everything I'm doing, and other times when I'm convinced the cause is so right? How did I get to be this way? It began when I opened the box-- the Leviathan box. I surrendered my will. I can't go on this way, seeing people hurt, people I've known and loved. I must find the strength to fight this. I need time. I must stall everything until I find the answer."
I take back everything I've said in the past about Barnabas' reversion to good guy having been badly handled because it's totally making sense with this viewing.

Michael is diabolical in using Maggie's terror and sleep deprivation (both of which he caused in the first place) to set Philip up!

Flashlights, people.  Flashlights!  Hey, did anyone have a Navy p-coat too like Philip's or Michael's?

I wonder if a part we didn't see during Michael's overnight stay was of him sneaking into Carolyn's room and... nevermind, I don't even want to think about it.

The female Leviathan followers have more staying power than the male ones.

DS and its 1960s sensibilities were nothing if not sexist.  Thank the gods for what they did with Julia in this storyline.

More like most satisfying moment.

I just noticed this follow up to the original list:

17 All-Time Great Cult TV Shows You Say We Missed

DS, ST, The Avengers, etc.-- now that's more like it.

Also included, er, not-included-but-acknowledged-after-fans-pointed-out-the-omission is Adrian Paul's Highlander series.

A friend mentioned that Dan Aykroyd and Margot Kidder used it on SNL in 1979, which was news to me.  I couldn't find it as a vid, but a transcript of their skit makes it easier to find anyway:
