My goodness, the script is absolutely superb... the episode (particularly the first half) is just a cascade of beautifully directed, beautifully acted, beautifully characterised and beautifully written scenes one after the other. These characters are so lived-in. The actors playing Ryan and Cesco are great - the scenes where they get into a conflict with their teacher are so naturalistic and realistic in a way that TV depictions of schools rarely achieve. Everyone is three-dimensional and there are lots of excellent directorial choices, particularly in the scenes where Catherine follows Clare and during the spousal abuse scene which happens off-camera and we see from the child's perspective. Great work by all.
