A thirteen-year-old boy wishes to be big, and his wish comes true. Except there's no time travel element, which really sticks in my craw. This kidult immediately lands a job in the big city and masquerades as a genius toy titan for an entire month? A thirty-something woman has sex with a pre-pubescent? The floor piano scene IS really cute, but was 1989 just a slow enough talent year for Tom Hanks to be Oscar-nominated for his perfectly ordinary performance?
