I watched Close Encounters when it came out in 1977. It was amazing -the effects, the story, the conspiracy to hide something in plain sight.
A lot of that still lives today in the back of some people's minds but for an almost teenager that looked incredible. I bought the DVD back in the late 90s and watched it recently on Amazon again. Of course is a lot different from our world now but the basics is still there - it is a good story.
I can still remember as a teenager at the theatre being absolutely spellbound at the early scene with Richard Dreyfus in his truck at the train crossing - the film had me in it's clutches from that point and it remains a sentimental favourite to this day.
Re-watched it with a 16-year old recently, and it hasn't aged well for teenagers brought up on modern CGI. Her view = meh.
But I still loved it!
