Yeeeeah Keamy doesn't get enough respect as an antagonist. My Keamy rant is this:
In a show where everyone plays stupid fucking games of subterfuge and nonsense with magic island warfare, Keamy just comes along and very decidedly goes "I'm not playing your dumbass games."
So when Ben's like "lol ya i dont care u got my daughter i dont even love her" he just kills her, boom. No games. Doesn't give a shit if Ben is bluffing or not. He's here to get a job done. End of story. Just mows down Others no problem. Just makes it clear he's here to do his job and he's not listening to anything else.
Keamy is just terrifying and effective and such a good choice because he is absolutely against playing nonsense island games and was such a unique element to the show during that season, and it's a shame it was during the writer's strike because he could have had so much more too.
I agree with this and he definitely stands out more when you binge the show. So much of the drama is just circular nonsense that leads nowhere to pad the seasons, but Keamy is like "yeah I'm going to get a bunch of marines and will shoot everyone LOL."
