Sometimes a film wins you over with its sheer exuberance and sweetness.

This is the real deal, and it shows up the likes of pre-Eighties Xanadu and Roller Boogie poseurs with a funky, grooving panache that's all its own.

It will remind you what it was like to be a teenager during the last few days of summer. And even though the plot is a little thin, you probably won't even notice until long after the music stops.

For the most part though, the honesty of the performances keeps everything afloat when it could drift into easy sentimentality.
