DTC's short-termism is to blame. It ran through everything he did: bringing back Kathy, introducing new characters only to give them nothing to do, killing off Lucy without thinking of the consequences, the list goes on. His one big innovation, the Carter family, started off very well but even they were completely repetitive and boring within just 12 months.
It feels like he only ever planned up to Feb 2015 and everything since then has been made up as they go along.

Yep. Most of his own characters were poor and as a result the show has had to fall back on the Beales and Mitchells to carry it. Both families have become tainted by their association with the Bobby cover-up and, in Jane's case at least, completely irredeemable. Lack of long-term planning strikes again.

He played his own fanfic on the show. He messed up history, he revealed long term secrets in the most dull boring way. He created Elaine. He killed Lucy and for what exactly? Killer Bob and Jane?
Kirkwood tried to turn the show into Hollyoaks
Newman tried to turn in the show into BoreEnders
DTC tried to turn the show into DTCEnders.
I can't even face watching the show anymore. I have watched since day 1 and I even have a bad taste in my mouth now when I look back and think of Den with Gavin and Vincent's Dad 
SOC need's to ditch more than the easy safe ones that DTC created he needs a late 90's/early 00's cast clearout.”
This.
DTC started off well but has left the show in a real state. Half of the cast are completely superfluous. SOC has got his work cut out.
