In terms of tone, Adam is closer to the Morph series than to the various grimy, often bleak worlds that Peter Lord had previously painted in shorts such as On Probation, Babylon and Going Equipped: Lord describes the central character as "Morph with genitals", but "Morph with weird religious overtones" sums up the film as a whole. Neither the full frontal nudity nor the could-possibly-be-percieved-as-blasphemous subtext prevented it from being shown on children's television in the UK, however.
The character animation is up to the usual Aardman standards; aside from Adam's brilliantly expressive face, there's the way his arm stretches and waves about like elastic after the hand tugs on it, and the way his head sinks into his neck (leaving his eyes in mid-air for a split second) to avoid oncoming balls of clay.
So, yeah - a witty premise, spot-on character animation and just enough thematic meat to get the film stuck in the mind. Not surprisingly, Adam bagged Aardman another Oscar nomination.
