@wrestlemaniac – I saw Infernal Affair. It was better in some ways, but also not as good in other ways. You get a much better sense of just how long he is actually undercover, which is never made all that clear in the Departed. There is a real threat surrounding his character not only with the danger from the mob, but also with him losing himself. He ends up being a function mobster way longer then he was a cop, which takes a toll on him. Leonardo DiCaprio’s version wasn’t as conflicted, he was just scared.
The Infernal Affair’s version of Matt Damon character is significantly different- much more conflicted. And there’s no Mark Wahlberg or Alec Baldwin counterparts, and those guys added a lot to the Departed, as did Scorcese’s filmmaking style. Overall, I’d say check it out if you’re up for dealing with subtitles.
