Oh, I would definitely put "sex" in there, too. Did you notice that he put his hand on the right side of her chest when she was feeling his heartbeat (Cumberbatch's put his on her left...when she objected, his intention was less clear-cut).
I was more struck in that last scene by the "kicked dog" aspect of the relationship the second time through. Miller really sold the conflict of both loving and hating Frankenstein. Which, I suppose, is also toddler-like.
I definitely saw the difference in reference (toddler vs. TBI) in the opening sequence, but more striking to me was that I swear I could see the thought process step by step with Cumberbatch and he didn't skip anything until he got up on his feet (walking should have taken longer, but I understand that they didn't want to spend a lot of time with falling down from standing. We can only go forward.) whereas Miller looked like he was recreating something he'd seen. It's a really subtle difference, and, like I've said, it was probably the "this is what we're doing in school" thing that really made it stand out to me.
