Doctor Who: EVERY Steven Moffat Episode Ranked Worst To Best

Speaking of satisfying finales, River Song is another character who Moffat closed off (for now) in a great way.

The dynamic between Alex Kingston and Peter Capaldi is so different to that of Kingston and Matt Smith, and yet, the chemistry and connection between the characters remains strong, and most importantly, believable. It's arguably their most natural bond, with their relationship becoming more mature than it was with previous Doctors, and yet no less fun.

To turn the tables and have River not recognise the Doctor was a great way to keep their storyline fresh, while also adhering to the established guidelines of their wobbly-wobbly timeline.

The final scene in front of the Singing Towers of Darillium is such an emotional rollercoaster, and god bless Moffat for leaving a little 24-year-sized loophole so that River Song can still make a grand return in the future. Here's hoping!
