The performance by the actor playing Dexter is very awesome. Dexter is a character who doesn't want to be seen but is always being watched. And Hall captured it perfectly. As you said, this is a unique perspective from the Killer/ vigilante. My memories of the IceTruck killer faded, but I think Dexter was impressed and fascinated by the killer.
It is going to get rough from here Strap in Bro.
