A recent discussion with a Toronto-based editor friend of mine about Steven Spielberg's 1977 science fiction epicish Close Encounters of the Third Kind got me reading up on the film. It's held in high regard today; generally. I have not seen it in many years: I was there when it hit theatres here in Ontario, Canada, but I was coolish to the picture -- a little disappointed. When "CE3K" premiered on television I found it interesting enough in that included were scenes not seen in the original release, but, again, I felt it to be good but not great.
For me there are more than a few almost-great feature films. The list could be huge, but I'm talking here of American mainstream films frequently held high. There are more titles, but this is a good start:
From Here to Eternity
Saving Private Ryan
Hot Rods to Hell
