Doctor Who: The Power of Kroll

About This Movie

So, 'Doctor Who: The Power of Kroll' is a pretty fascinating entry in the series. You’ve got this mix of action and adventure set against the backdrop of the marshy moon Delta Magna, which has a real gritty atmosphere. The conflict between the Swampies and the refinery crew is central, and it really pulls you into the tension. The performances, especially from the regulars, have that endearing quality, even when the pacing feels a bit uneven at times. Practical effects are a bit dated but they add a certain charm; the Kroll creature itself has a unique design that stands out for its era. The themes of environmentalism and conflict over resources resonate, even today.

This episode is part of the Key to Time season and has seen varied format releases over the years, which has affected its availability. The scarcity of certain original broadcast formats makes it interesting for collectors, especially those focused on classic Who. There’s a niche appreciation for how this story blends ecological themes with the trademark Doctor Who storytelling, and the unique setting definitely appeals to collectors who enjoy the more offbeat stories from the series.
