Watching Four Lives... Just finished ep01 
Stephen Merchant, the lanky comedian is quite remarkable! 
I binged watched all three last night (if you can binge watch three

) Agreed on Merchant, Sheridan Smith too.
I thought I was gonna be spending a lot of time location spotting as a good deal of it was filmed in my home town, but I was engrossed in the story

I won't comment further as you haven't watched the other episodes yet
