Agree with both. In Bernard's case, I think you've hit the nail on the head; you could even make that kind of behavior more sympathetic if perhaps Bernard explained to someone that his wife knew he wasn't happy in England and he was only there because he loved her. i.e. she didn't do it out of spite, but because she was genuinely afraid of losing him. And he could regret having never really assured her otherwise. Again, this is something that just a teeny bit more dialogue could help with IMMENSELY. (The bits with the translator are funny, but they don't add anything to the story - trim one and give us more character detail instead! Sorted. ;) )
Same goes for Chloe's mother; why can't we have a moment where Chloe doesn't excuse her mother's behavior, but tries to give Gus some context? Context is EVERYTHING.
