I personally think Mulholland Drive is the best US film since the original Manchurian Candidate. I did like Before Sunset and its sequel. I'm tempted to say that together they're greater than the sum of their parts, but the sequel was a little unnecessary and didn't stand on its own two feet. I also wish it hadn't told us so much of what we didn't see (and didn't need to see) in the first film. Nevertheless, both films were filled with moments that any scriptwriter would've loved to have written, especially the record store scene in the first one (w/ the listening booth) and the fight in the car from Before Sunset (which was scarily good.)
