I don't know why, but The Departed seems like a jumbled mess of scenes, as if they only picked certain bits from IA, and then made shit up for the rest of it. The lil' individual cuts for the stars to ham it up, the car park finale, the forced love triangle, all unnecessary, but most importantly the arc of the character change in Ming/Sullivan is removed entirely, and that's what IA was all about.
So, it's a poorly executed remake, that puts Matt Damon, charmless fucking prick, into what was the important character, and that it doesn't star Chinese Bob Hoskins Eric "Fat Sam" Tsang, so yeah, IA for me every time.
You can read this ? You've helped ruin the place.
