A shoestring dirge, ruined by hopeless plotting (radiation sickness, anti-radiation drugs, hapless Daleks) and a wince-inducing Roy Castle turn in “comedy” support.

Not only has this movie a sound moral but also a quaint Flash Gordon charm because of its fanciful sets, Cushing, Hammer's reliable Baron Frankenstein, is properly whimsical, and Gordon Flemyng's amiable direction wisely avoids camp.

Daleks' Invasion Earth 2150 AD, the sequel, is even better, but the two Who films still make an engaging kiddie matinee double bill.

[UPDATED 2025 4K + BLU-RAY REVIEW] The film is pitched directly at small children, but it works on that level.
