I did forget Harrigan goes up the ladder first.
As I said earlier, the spear itself isn't a big issue, but it's the straw that broke the camel's back while watching. It's not so much that he doesn't seem worried about that injury as he doesn't seem to care about getting injured in the first place.
That lack of a sense of self preservation, coupled with his lumber-on-the-ground-toward-the-enemy approach, all goes towards feeling like Jason with a cloak. He doesn't feel like a character, he feels like a movie monster.
To me.
