I thought the second hour was almost superfluous. Like, once we knew Henry was it, that was all I really needed, even if I kind of liked his creepy obsession with Abby.

But Abby had to kill him - they've been totally committed to the cheesy conventions of the horror movie, and the final girl always kills the bad guy in a supposedly safe space (the classic is somewhere inside, but the island is her home) with a phallic object. I knew the moment we saw her kneel down next to the blade that she was going to get Henry with it!

I'm on the relying too much on "they're just psycho" side, at least for Henry. We knew Wakefield was psycho coming into it, so that was fine, but the Henry switch to killer was a little lacking in reason.
