Adapted from Irvine Welsh's 1993 cult novel, ''Trainspotting'' is one of the best films about drug addiction. Starring a young Ewan McGregor long before his Obi-Wan Kenobi days, and directed by Danny Boyle long before his promising career has crashed and burned with flops like ''A Life Less Ordinary'' and ''The Beach'', the film has been described as ''a singular sensation, a visionary knockout spiked with insight, wild invention and outrageous wit'' (Rolling Stones), ''exciting, energetic, thought-provoking (...) a kinetic movie, where everything, including the camera, keeps moving'' (James Berardinelli), and ''a desolate, fast, funny, scary film'' (Michael Wood, Slate). But, above all, it's a comedy, with classic lines like: "Take the best orgasm you've ever had, multiply by 1000, and you're still nowhere near it", "Fuck it, we would have injected Vitamin C if only they'd made it illegal", and "I hate being Scottish. ... Some people hate the English, but I don't. They're just wankers. We, on the other hand, are colonized by wankers. We can't even pick a decent culture to be colonized by". And it's a sexy movie as well, with Kelly MacDonald (''Gosford Park'') in a hot erotic scene with McGregor. But ultimately, what makes this film so great is the realism with which the drug culture is depicted. It's not pretty, but it's not boring neither. We definitely don't want to live like them, but then again, we can definitely understand why drug addicts are living like that. It's not a pro- or anti-drug movie. It's better than that. It's honest.
