When Dan Bush (Co-Writer, Director, Co-Screen Editor) and Conal Byrne (Co-Writer, Main Character Actor) sat down to put this project together, I'm sure they were enthusiastic and knew they had an interesting story to tell. They do.
However, either because of run-time editing or they were negligent in the telling of the story, the viewer is given too much information too soon in some ways (first plot twist revealed at about 19 minutes in; second at about 31 minutes) and not enough information too late, if at all, in other ways.
Meanwhile, one has to fight against the sleep inducing, hauntingly slow, lullaby-like synthesized keyboard and "rain-on-a-pond" two-fingered piano poking that carries throughout the entire film.
The cinematography adds to the vertigo of sleep in that, at no point does it seem, the camera operator/director can make up his/their mind if something (other than Conal Byrne) should be or remain in focus. There are a few times when we are seeing things through another's failing eyesight. Fine. But that wouldn't justify all the other times.
There is a cast of characters in this film but we don't get to know them or care about them except for Amy Seimetz's character, "Jules". Ms.Seimetz did an admirably fine job to establish her character and insert "Jules" into the viewers consciousness despite so little screen time.
Conal Byrne performed very well with the different but somewhat similar personalities he had to keep distinct for the viewer. I'm not surprised, however, since he co-wrote the story and didn't have to create the character after landing the role since he wrote the role for himself. Nevertheless, he showed skill and talent in his portrayals.
This film is categorized as "sci-fi"/"drama" in the same respect 'Flowers For Algernon' is. But this is no "Flowers For Algernon"... would have been nice if it were as 'William Zero' is only part way to achieving was was achieved in 'Algernon'.
"The Reconstruction of William Zero" shines as a story but this sleep-inducing version of it begs an awakening in a remake.
