The death of (spoiler)
The death of Esme was a welcome surprise. I wasn't expecting it, and didn't even believe it until I started episode 5 and they had her funeral. I hope there isn't some trick and she comes back. I really didn't like the character and how she acted. Alfred has better options.
I'm genuinely pleased that end of 4 "cliffhanger" turned out to actually be something. And Alfred banging Sandra at the bar at the end of ep 5? Well done, sir!
