Barry Langford, writing in the "J. R. R. Tolkien Encyclopedia", noted the film's deficiencies, including the "glaringly evident" weaknesses in the rotoscoping animation. The quality of rotoscoping from filmed live action is limited by the quality of the acting, which, given the lack of rehearsal and time for retakes, was not high. The prologue was not rotoscoped, but shot as "silhouetted dumb show through red filters", revealing clumsy mime and confused voiceover, announcing that Mordor defeated Elves and Men at the Battle of Dagorlad, which Langford observes would make the rest of the action incomprehensible. The small budget led to underwhelming battle scenes, as in the Mines of Moria where the Fellowship is confronted by what looks like a very small force of Orcs. The rotoscoping varies from strongly drawn to almost absent, leading to a markedly uneven treatment through the film. The characterisation, in Langford's view, similarly leaves much to be desired.
