For what it's worth, season 5 is the worst so far easily. Season 6 has a few questionable moments but it's more focused and almost entirely writes out the worst plotline.

I do legitimately want to know how free healthcare kills the poor, though.

Cottonmouth was the episode for me. Told you everything you needed to know about Boyd and why you should give a shit.

I graduated from Sussex this year. Watching this episode, I had to contend with the fact that Sanjeev Bhaskar's brief, red-haired guest role meant he wasn't there to shake my hand. I was hoping his role would be just a little more substantial to make up for it. :(
