They don't do it well. I'm not sure what the comic's like, but the desperate intensity of the film is absolutely lost.
The whole thing feels like it was made by film students who watched a bunch of cool TV shows and then decided to take all the "cool" scenes and string them together. It's a late 90s TV sci-fi with more budget and by God did all of that budget go to Jennifer Connelly because they sure as shit didn't spend anything on the special effects.
There is no drama, there is only m e l o d r a m a. You could have a character fart in this God-damned series and someone would react like it was a direct insult to their entire lineage.
