I think that's a pretty average rating for Unforgotten. I said it might not do as well, but it would've been nice to see it over 6m. However given its got a good resonce it should stay at least over 4m next week against TA, although will drop for the 1st showing as BBC1 have no +1.
POG dogs did well, up on last series I think, which got 3.9m against DIYSOS. And up on Flockstars with 2.3m more viewers.
One interesting fact: In 2013 on Thursday ITV launched Breathless with 3.4m, in 2014 ITV launched Chasing Shadows with 3.58m, in 2015 ITV launched Unforgotten with 4.7m. Going in the right direction at least, and last night's drama was better than both of those.
