While I understand the premise, I do find it a bit ridiculous that appropriate fail safes wouldn't have been part of the original programming, so that a holodeck construct wouldn't be able to reach consciousness and call for an Arch. That part really annoyed me. Seems like such an irrefutable and unmitigated standard to deploy in holodecks.
Daniel Davis is an underappreciated talent.
I haven't much to say about the episode itself except:
A very interesting "What is conscience?" All wrapped up in a 19th century London setting. Very interesting concept hidden in an interesting storyline. So far the best episode so far for me. Also Data lost.
Early in season two we get one of my favorite TNG episodes.
Yes, it is up to debate if Moriaty should have been able to achieve this kind of power from a simple mishap. But I think that is the one concession you have to make in an episode that asks, in essence, the question if conscience and self-awereness equals life. A topic very much Star Trek.
I really enjoy Daniel Davis performance as Moriaty. He is perfect for that role.
I think you can say that definitely got the better of Data
