T2 Trainspotting (2017)

Katie Walsh The referential treatment is wise - it's truly the only way a sequel like this could get away with existing.... That interrogation becomes a quicksand in which the film is repeatedly and unfortunately bogged down.

David Edelstein Although T2 Trainspotting has a melancholy streak, a nostalgia for a time of crazy energy and resiliency, Boyle seems desperate to prove he has lost none of his youthful giddiness and that he can go home again.

Tim Grierson "T2" questions its own existence, proving just satisfying enough by being as unromantic as its predecessor. The first "Trainspotting" was about the horror of heroin, while "T2" argues that nostalgia is just as addictive a proposition -- and just as toxic.

Peter Travers The passing of two decades can take the piss out of these era-defining Nineties rebels. Still, there's a hard-won wisdom at work here, as well as an aching sense of loss. .

Kate Taylor A wittily self-referential romp about the disillusionment of age.

Scott Tobias It never comes up with a coherent answer for why it exists, other than to indulge in the same nostalgia that its characters find so toxic.

Jeannette Catsoulis While "T2" might be middle-aged, it's very far from moribund, the despondent base notes shouldering a story of revenge and regret, amity and acceptance.

Liz Braun Anyone who loved Trainspotting needs to see T2.

Peter Howell There's something reassuring about how little Sick Boy, Begbie, Spud and Renton have learned about life in the past two decades.
