I feel that the producers have listened at least a little bit this year. They're doing normal nominations, not protecting certain Housemates by making them immune and normal shopping tasks. Also we're seeing more genuine dialogue between the Housemates (like the conversation about the EU referendum) rather than just manufactured drama.
Obviously there is still room for improvement (I hope the 'Who is the ____est Housemate?' tasks stop soon) but things are definitely far better than they have been the past two years. Keep it up, BB!
