What I didnt like was the changing of the origin of the Leviathan's

[spoiler]Oberson was the original leader and the Leviathan's were from an otherwroldy dimension.  Then because of fan reaction, they decide to "retcon" the roigin so that Nicholas Blair was always the leader and the Leviathan's were in league with the devil.[/spoiler]

I was surprised they used filmed images of real bats for Mrs. Johnson's dream instead of the bat on a string.

They probably had to mention the Sebastion/Jeb resemblence as Jeb was carolyn's husband and she was still in mourning.

Yes, [spoiler]there were only three Collinses living at Collinwood after 1795.[/spoiler] Perhaps Joshua hired a new governess for Daniel and a nurse to care for Millicent.  There were the other servants like Riggs, maids, and the cook still in the house.
Ben was probably also there from time to time when he wasn't at his own house/land.

Joshua & Millicent still may have been alive when Daniel married Harriet.  The supernatural seems to be dormant for a few decades before acting up at Collinwood again.  Perhaps there was a pleasant athmosphere when Quentin & Gabriel were children.

Amy had a "Black Beauty" book in one episode.   When Willie is sick in the early Barnabas episodes, Roger thinks he is pretending and says something like "Sarah Bernhard" would be envious of your act".

Phillip Todd mentions the Moon landing in another episode.  Carl talks about his trip to Atlantic City and salt water taffy he bought there in 1897. 

in the 1840 Concordance, the late Authur Warren Oddson had some great ideas regarding the 1840 inconsistencies.

I wonder if viewers at the time thought Diana Walker would be a permanent replacement as Carolyn Stoddard.

This substitution was similar to Vince O'Brien playing Sheriff Patterson for an episode and Dana Elcar re-appearing the next day.  Though O'Brien filmed that episode after Dana Elcar filmed the next one.  Too bad Elcar didn't stay, he was the best sheriff.  Though post 1795, the character hardly ever appeared.

I did like the second Harry Johnson better then the first.  I couldn't take Craig Slocum's acting, it was terrible.
