Worst. Tag line. EVER...
'He and she were thumb-trippin'. They had the makin's... and the tail-end of summer.'
I rest my case...
I got not one, but TWO that're worse.
"In the era of cool, he was the soundtrack." (Beyond the Sea)
"Twelve is the new eleven." (Ocean's 12)
Not to disagree with you about the quality of Amblin's tagline, as it is pretty bad, but I just thought I'd add in some that I thought were even worse.
