The best thing about this film is also the worst thing about it. It's very visually distinct, in a similar way to the modern day Dick Tracy film. It looks like a colourised black and white comic book come to life. It's also set in an odd world - a post-war era where technology has progressed in exotic ways.
You could imagine a boy in 1940's america reading these stories as the sci-fi of the era.
Sadly, the look of the film is achieved with some CGI which really takes you out of the action when it doesn't work... and it often just looks like the actors are superimposed over the CGI, which is a shame.
That said, as Gwyneth Paltrow films go, it's not one of the worst, and even the cheesy catchphrase of "Good Boy Dex" only grates slightly.
Then main take-home message of this film is that Angelina Jolie really does have a very pronounced fold in her bottom lip. My current theory on this is that she once (as I did) rested her soldering iron temporarily on there, in the manner of sucking a pen.
It's a theory!
