The latest film to boast both state-of-the-art computer animation and 3D effects is Monsters vs. Aliens from Dreamworks. The premise is as simple as its title suggests – when aliens invade earth the government fight back with a bunch of monsters that they have been secretly hiding from the rest of the population. The monsters are all loosely based on classic 1950s horror monsters. There is a giant woman, a giant insect, a mad scientist who has turned himself into a cockroach, a gelatinous blob and a reptile man. The alien invaders and their robotic warriors also evoke 1950s science-fiction classics such as The War of the Worlds, It Came from Outer Space and The Day the Earth Stood Still. The result is a fun blend of action and humour yet the film can only really be described as mildly entertaining.
