The majority of people who have a problem with Sam are saying he's been a dull housemate and are not focusing of his hearing issues. Reading the OP, I feel as though you are pretty close to defining Sam by the hearing issues (which is rather patronising), yet you are asking people to 'come up with an argument that does not involve a person's imperfections'. Sam seems capable of looking after himself and I somehow feel he would not welcome focus on his hearing. Notwithstanding, Sam has failed to make much of a positive impact. He does seem rather immature and sleepy, with very little charisma.
