I hope Kane makes an appearance in this or in a sequel. I always thought he was an awesome character, even if the whole "detachable hands" thing is pretty silly.
I thought they did a good job of making him extremely unlikable through the torture scene. He's not a powerhouse player, but he was exactly what we needed him to be in this movie.
Same, he made you dislike him and want Deadpool to beat him/ take him out. He was really menacing in the torture scenes, especially when he carried on torturing Wade once his mutation activated simply because he wanted to.
And the first confrontation between Deadpool and him on the freeway was badass, with him simply not caring about 'Pool.
Oh he's serviceable for sure. It's just that he seems to basically be an up-jumped(for you GoT fans) henchman masquerading as a boss. As one and done's go he's fine.
