That's nothing --I was lining up around the block on the first theatrical opening night in December 1978 for 'Superman The Movie'. That was when I was still reading pre-Crisis, Bronze Age comics inked by the likes of Curt Swan et al. I like both version of Superman - Donner's and Snyder, specifically Superman ('78), MOS and BvS.
Even earlier I was there for the likes of Star Wars, Close Encounter, A Bridge too Far, The Spy Who Loved Me, Saturday Night Fever, Smokey & the Bandit -- top 10 grossing films of the 1977 IIRC and all of them I went with my sister , bothers and cousins. I went on the average of once per weekend to the theatre. heh. I think that I'm one of the only few SHH posters who have seen these films in all its unvarnished glory.
Of course I saw Burton's Batman in the theatre.
These days, the youngsters can enjoy all their Disney/Marvel outing. They will soon venerate Uncle Walt. lol
