Two 1990s teenagers find themselves in a 1950s sitcom where their influence begins to profoundly change that complacent world.

This is a surprisingly strong role for Reese Witherspoon, who tends to be an overrated actress. If anything, she is actually underrated here for how well she made Jenny her own character. The appearance of Don Knotts is a great touch, and William H. Macy is wonderful as always.

While a simple concept (kids getting sucked into the TV), the execution is a work of genius. Writer-director Gary Ross used this backdrop to explore race relations, the "good old days", changing cultures and mores... and exploring a range of "right and wrong". And underneath it all, it still remains a sense of humor and does not attempt to guilt trip the audience.
