That part when Alan comes back is very heartbreaking, wondering where his mom and dad are. And when that man in the factory tells him he still sees the Parrish's from time to time, and Alan goes to see it's their graves, so sad.
I laugh so hard when Carl sees the 3 monkeys go by on the motorcyle, when he's handcuffed to the police car, while Alan's driving, his reaction is priceless!
I agree, it was great how it let them have the childhood they had originally missed out on, yet kinda cool they were able to remember everything that had happened, so they could change some things. Like Judy and Peter's parents dying, Carl being fired, the factory going-under, and so many losing their jobs.....
