“T2: Trainspotting” (***1/2 out of four) was an electric sequel to the 1996 cultural phenomenon picking up 20 years after the events of the original film as Renton (Ewan McGreggor) returns to Scotland and reunites with former pals Sick Boy (Ewan Bremner) and Simon (Jonny Lee Miller) while the psychopathic Begbie (Robert Carlyle) escapes from prison and comes after them for revenge. Director Danny Boyle ably duplicates the original’s fever-dream style and laces it with a razor-sharp script that is alternately funny, thrilling, and haunting at times. All four original cast members are terrific and recreate their chemistry from the original as they all transition into middle-age, with Bremner a standout this time around. What might have been a needless nostalgia trip turns out to be Boyle’s most entertaining film in years and a tribute and wild continuation of the original. Bullseye!
