The studio responsible for this unusual series are also the creators of Ergo Proxy, which is the best anime I've ever watched, story and art wise, so I may have been expecting a little too much. Speed Grapher is the story of a photographer who gets involved with investigating a seedy club, when a young girl known as 'The Goddess' kisses him he suddenly develops the ability to make things explode with his camera and sets about freeing the girl and discover what exactly has happened to them.
I watched the first episode online and was rather impressive, the animation was smooth and the story very original and it was interesting to watch as the characters and plot developed. Unfortanutely the animation begins to slip from there on, and that's what stopped me from giving this a fourth star.
The voice acting is in fact very good, each character is portrayed better through their voices than their actual expressions, which is a shame when the first episode was so good. Now, on the fourth disk, the animation feels clumbsy and very amauteur, in fact Oban Star Racers had better flowing scenes and character interaction than Speed Grapher. If they spent less time focusing on the sexual element of the series, then perhaps the animation would be a little better.
But the plot and voice acting does save it, getting across what needs to be said, while the animation tries to keep up. I once read a review that this was like Cowboy Bebop meets Se7en, and it does in fact feel very much like the combination of the two - just not as stylish as Bebop or as clever as Se7en. But it is still an enjoyable anime, though I recommend watching one or two episodes online before making any major decisions to buy this boxset.
