Three films on this list do not meet that qualification: "Blade Runner," "The Shining" and "The Truman Show" don't qualify under the definition of blockbuster. "Blade Runner" was hardly a success in its first release (first summer, roughly $15-18M total take against $28-32M production budget sans marketing) and barely put a dent into it's production and marketing costs… it was virtually ignored in favor of E.T. by most moviegoers at the time. "The Shining" barely made a dent into it's production/marketing budget in its first weekend in 1980, it only crossed its $19M production budget years after release once folks found it (and re-appraised it) on video (VHS). "The Truman Show" also had an enormous production and marketing budget (production was around $95M) and over several weeks did not make that money back (again, VHS and later, DVD earned more than theatrical). It did a healthy $51M against that budget in its first two weekends, but had an enormous drop-off thereafter and didn't recoup its cost domestically.

Lastly, if you're going to talk about theatrical blockbusters, then stick to talking about the theatrical version in release at the time… You come close to calling Blade Runner's "best" scene the one with the unicorn and that most certainly doesn't qualify as it only became evident (much later) on video. So much for that definitive answer circa 1982.

The film also saved the "Star Trek" franchise after the debacle "Star Trek: The Motion Picture": without "The Wrath of Kahn", "Star Trek" might never exist today. When adjusted for inflation, it is the most successful "Star Trek" film (before JJ Abrams started it over with his tripe). To not include it in this list is moronic and to include another 1982 summer release "Blade Runner", a great movie but a commercial bomb, instead is journalistically negligent (in a film criticism sense) on all your parts.
