Elektra, both the regular and director's cut version, is not a great movie. Jennifer Garner does her best to inject life and personality into a film that is both weird and strangely lifeless. The action, such that there is, does little to thrill. When your heroine literally fights white sheets you might have a problem. That being said, Garner is fantastic, the film has a strange charm to it, and it doesn't make her character merely eye candy.
WARNING: If you bought this thinking that you could get the director's cut digital copy you will not get it. This comes with the standard version of the film. I had to email, call, and speak with management before this was made right. So if you want the director's cut on digital and don't want to work your way up Fox's management then maybe just buy the digital version.
