Hamlet 2: The play-within-the-movie's good, but everything else is an emphatic no.
Let the Right One In: I don't know. I respect many of its decisions, but I don't think I liked the damn thing.
Miller's Crossing: No. Seen it countless times over the years, and still every little detail in the movie seems (and feels) completely wrong to me. Whether it's deliberate or not, I dunno, but it does mean I never like it no matter how convinced I am that this time, things will change.
Slumdog Millionaire: Yes. Not to a degree that will find me singing rapturous threnodies to its glorious golden brilliance from an L.A. rooftop at four in the morning, but it's the most consistently not-awful film I've seen from Danny Boyle since Trainspotting, which must count for something.
(Told you it'd be brief.)
