Glad I'm not the only one didn't realize the Leviathan storyline was cut in half. I own (and have by and large, read) all of HP Lovecraft, so I really WANTED to like this storyline. Wish I could have liked it more. The start was good, and as has been said, if it was intended to be longer it explains the slow start. They could have gotten a lot more into the science fiction/horror aspects, and some of the whys and wherefores.
Paul Stoddard's backstory also got short shrift, and it would have been good to get more character development. Goes without saying that more emphasis on the Liz, Carolyn and Paul situation and the current externally driven conflicts would have been interesting.
After all the teasing with the subplot of bringing back "Grant Douglas", to do virtually nothing with the character once he's himself again is a terrible waste. Outside of Professor Stokes, he has the most knowledge of the occult of anyone we've seen. He probably added even more to that in the 70 something years since he left Collinwood to avoid Petofi. But instead, the character serves no plot purpose other than to hold up walls and look pretty.
I'm partial to a mental image I have of Prof. Stokes asking his old doctoral advisor to come consult on this. An "expert on the occult, and obtainer of ancient antiquities" he and Quentin are trying very hard not to let it slip how often they've encountered each other before.
And don't even get me started on the nonsense with Peter Bradford's ghost.
