Critics Consensus

Choppy logic and uneven performances are overshadowed by not-so-special effects that makes the suspension of disbelief a nearly impossible task.

Good idea unsuccessfully realised with Ed Burns doing his best.

At the risk of making an overly broad and limiting generalization, it's generally wise to make sure an action movie's plot has actually kicked into gear by the time the first hour has elapsed.

It's somehow refreshing to know that the spirit, if not the flesh, of Edward D. Wood Jr. lives on.

Based on the Ray Bradbury short story of the same name, this is a colassal disapopintment - unworthy of the memorable source material.

The special effects are on par with a basic film you'd see about a giant squid on the Sci-Fi Channel, and the story is just as boring.

In case you didn't know, this movie is adapted from a short story of the same name by the great Ray Bradbury. Bradbury reportedly was pretty happy with the film, which surprises me, because it's a real dog. While it started off rather promisingly, by the second half it had degenerated into a ridiculous creature feature. The otherwise talented director, Peter Hyams, reportedly had a budget of only $30 million to work with, and it shows. Primitive CGI, unconvicing miniatures, and very bad use of "greenscreen" all contributed to my inability to take the movie seriously.

Tem uma trama basica e por um momento aparentemente inevitavel mesmo com atores medianos temos uma boa equipe e um bom elenco. Os efeitos são o ponto mais detestavel do filme provavelmente por falta de recursos financeiros. Acredito que um remake com um grande investimento pode gerar uma franquia e tanto

Poorly executed attempt at a classic Bradbury story. Well, on second thought, Bradbury's story was... executed.

This is supposed to be based on the Ray Bradbury story of the same name. Bradbury is one of my all-time favorite writers and the reason I started writing speculative fiction, so I am truly upset. Like the movie The Box, there are lots of extraneous scenes and characters. Just added so they could get their one hour and forty-five minutes in. Read the short story, or go to Amazon and look up the Ray Bradbury Theater series and see it there. And the poor special effects. You can tell the characters are in a studio with a green screen. It seems that they are moving in place to look like they're walking down the streets of Chicago (I think that's where it takes place). The only reason why I found this was because I was looking to see where I could read the short story and this came up. Some of the twists were OK but the rest of it just goes into cliche' end of the world science-fiction.
