The Good Son
I just watched the last hour of The Good Son, mainly so I could see the part where Mom drops her son to save her nephew, and I was struck by the difference in acting ability between Macaulay Culkin and Elijah Wood. I'm sure no one today would be surprised that Wood is a far better actor than Culkin, but seeing them together like that really made Wood stand out. And this was during Culkin's heyday. He was good in Home alone, but he probably should have just stopped there.
