“Transcendence” is a failed sci-fi morality tale by first-time director Wally Pfister (Christopher Nolan’s cinematographer). Johnny Depp stars as a researcher in the field of artificial intelligence who is developing a computer that will feel and think for itself. As he closes in on his project, anti-technology extremists attack him and shoot him with a radioactive bullet and, with only a month to live, he persuades his wife and best friend to upload his consciousness into the supercomputer. When his virtual form connects to the Internet, he grows in knowledge and capability, merging with other computers around the world to create an omnipresent entity that soon spirals out of control. Though Pfister’s direction is top-notch and the story line intriguing, the film as a whole is dragged down by poorly executed subplots and Depp’s almost somnambulistic acting — almost 360 degrees from his over-the-top roles in the “Pirates of the Caribbean” franchise. Still, it’s a fun outing.
