Film Threat by Pete Vonder Haar

What really grabs your attention about Undead, however, are the effects. For a movie budgeted under $1 million, the Spierigs have done an amazing job putting together believable visuals.

Precociously inventive horror pic that combines brain-eating zombies with outer space aliens.

A campy, low-budget Romero homage that's badly in need of editing.

There's nothing under the goofball gags and gushing gore, and its welcome is worn out well before it's over.

L.A. Weekly

Flesh-eating fish notwithstanding, Peter and Michael Spierig's low-budget schlock-horror parody brings precious little new to the undead genre.

The Hollywood Reporter by Michael Rechtshaffen

The over-the-top tone gets stale awfully quickly -- especially once it becomes clear that it's all wacky style over any real attempt at substance.

The New York Times

In the end, the film is a stale, derivative mess that borrows heavily from every zombie and alien movie worthy of imitation, to only ho-hum effect.

However visually striking, this Australian film is ultimately as tedious as it is derivative.

Village Voice by Michael Atkinson

Watching it is a smidgen like listening to the same monkey-walks-into-a-bar joke for the 105th time, but for the Spierig brothers, it is clearly a demonstration of fast-cheap capabilities and a one-way ticket straight out of Queensland.

On the level of a no-budget student film in which the shots barely match up into sequences. It's about as much fun as watching blood dry.
