“London Rampage” (** out of four) was a stylized but empty melodrama shot in B & W that plays like low-budget Guy Ritchie; in East London, a young man (Greg Burridge) returns home after 10 years and finds the city in disarray from drugs, gangs, and illegal underground fighting and finds he must journey through the city’s dangerous underbelly in order to protect his younger brother and help the rest of his family. Lots of violence and hand-to-hand action in the vein of “Lock, Stock, and 2 Smoking Barrels”; just don’t look for much in the way of character development or subtext. Burridge also wrote, directed, edited, co-created the music, and executive produced.
