He's not everyone's cup of tea, but after going back and forth about this a few times with different watches I've decided he's mine (oddly enough).
Detractors call him stiff (and he is) and aloof (I get it), but those are choices that make sense when you understand the logic behind his portrayal. "Unsocialized" doesn't [always] have to look like "unhinged;" it can also look...detached, hyper-rationalizing, wheels turning in head at all times.
^^^ And that would get old were it not for the fact that Lovett plays that vision very methodical and consistent so that it can all be undone in the final lair. His Erik's arc is calculating/processing by imitation -> learning how to feel organically. His tension: "Oh shit, I'm actually feeling things. I wasn't supposed to feel things."
Slightly hard to tell bc of the glare in the boots, but 95% sure he embraced Christine back (hesitantly) during the kisses/hugs and also held AO'B's hand, and that decision matters for his portrayal (saves it from being too stiff and consistent and he plays it like he's embracing her despite himself--stopped thinking, started to feel).
Also has to be paired with the right Christine, which he was with Anna O'Byrne. She got it; they played off each other well.
Forget Raoul, that veil is Lovett's real antagonist in the final lair.
