As an old-fashioned plot picture unhampered by artistic pretensions, The Day of the Triffids is above par for the course.

A sci-fi thriller (1963) that sticks in the mind, thanks to deft pacing and a vividly paranoid premise.

Although riddled with script inconsistencies and irregularities, it is a more-than-adequate film of its genre.

It's a good siege narrative, with uneven but sometimes very effective effects.
