17 Again really does look like the perfect family movie for anyone who has short-term memory loss and can’t remember Big.

Or Vice Versa. Or Freaky Friday. Or any film which shares a basic plot function with 17 Again. But it must be doing something right, because 17 Again is the top movie at the weekend box office.

Zac Efron as the weekend box office number one, Miley Cyrus as number four. Way to make everyone feel old, Hollywood. Honestly, they may as well have renamed 17 Again as Your Time On Earth Is Finite And Soon All Will Be Dust, Ashes And Dust.
