Like the GP said, they were bland, sort of jerks (and not really even Jerks With A Heart Of Gold), and had no chemistry together. As far as I can recall, they just had petty drama all the time that felt like it was written just because there’s supposed to be drama.
To me, they seemed closer to normal people with normal relationships that yes, have some conflict too. Especially in a small group living together all the time where majority is not submissive, so will assert themselves here or there.
