A modern take on the Frankenstein archetype story. Reason #1 to riff this movie: it stars Keanu Reeves, who I am convinced is a piece of 2x4 lumber dressed in human skin, doing his one-note method acting. Reason #2: certain gaps in logic appear in the film, such as how it takes exactly 17 days to clone a human as he or she appeared at the time the DNA sample was taken, but each progressive day accelerates the aging process. That's just one gap, but there are plenty others scattered throughout the movie. Reason #3: plenty of pauses between dialogue and quiet moments that are perfect for riff-insertion. Watch the movie and judge for yourselves.
