Herrvonspeck’s review published on Letterboxd :
T2 is kinda weird as it's structure is similar to the one of Trainspotting with it's bits and bobs all over the place, but the red thread, which heroin provided in the first one is missing. They also dialed back the grossness, which was probably a good decision since we all saw SAW and other stuff at this point and T2 couldn't have shocked anyone anyway. As a result the imagery is not nearly as powerful as in Trainspotting. I am not really disappointed in T2, but it's impact on me is certainly smaller, than the impact of Trainspotting.
