I'm assuming I'm the only one who really likes...
...Miller. :D
But honestly, without Miller there would be a lack of humor. In addition, his character gives the show a special touch. I think 'Gravity' has a unique style and it's too easy to complain about the 'cheap' look and certain characters. I would not consider me as a true fan of the show, but after 8 quiet entertaining episodes, I'm still wondering where that show will go. And I mean that in a positive way, because each episode managed to approach a special way of drama mixed with grotesque humor. And therefore, Miller suits perfectly in.
