I mean without Melanie there is almost no reason to watch this show anymore. I mean Sean bean was a superb this season. I do feel he lost a bit of his unique psychological aspect at the end but non the less fantastic unique villain with a fantastic god complex. But Melanie was the heart and soul of this show. It just won't be the same without her. Especially with Leyton taking her role I think we all know about his acting in the show. Also the way she left the show feels like the producers couldn't get her back to finish shooting the show. She will be missed.
