Nicola Walker is one of my favorite actors period but so is Sinead Keenan! Sinead will always be "my Nina" from Being Human. I'm American but I only watch international shows don't know why I just do. Sanjeev Bashkar is so brilliant as Sunny and his performance in season 4 and season 5 had me literally ugly crying. Not sure why the BBC ended his other show The Indian Doctor absolutely loved that show. The story's in Unforgotten are some of the best writing along with their ability to cast actors that bring the best performances to the table. I know most viewers aren't comfortable with change to a show they enjoy but change is vital for survival. Unforgotten is a show I can watch on repeat. I'm looking forward to Sinead Keenan being part of the team.
