Doctor Who: EVERY Steven Moffat Episode Ranked Worst To Best

After seven years away, Steven Moffat's grand return to the Whoniverse is a standout episode of Ncuti Gatwa's first full season.

Boom has all the elements that make for a perfect Doctor Who episode – high stakes, dark, thematically rich, emotional, but also comedic and light-hearted at times too. The single setting could have resulted in a static, boring story, and yet this only serves to heighten the tension and the mavity of the situation.

It genuinely feels like the Doctor is in danger, like the Doctor is out of his depth – which isn't easy to pull off.

Add in some brilliantly snappy Moffat dialogue (and Ncuti Gatwa's terrific delivery of that dialogue) and you've got one of the best episodes of Season 1, and one that rests comfortably towards the upper end of the Moffat pantheon.
