I find it interesting that so many of us equate the "best decade" with the decade when were in our late teens/ early twenties.
I think it's likely because we were becoming more independent, figuring out who we were as people, and were generally optimistic.
And then RL adulthood kicked in. I set my cutoff at 1985 because, although there were other good things that happened after that, 1986 was when my grandfather died, and he was one of the people who raised me. That changed the family dynamic drastically.

It's like the answer to the question, "What was the Golden Age of Science Fiction?" "12."

Well, I
was 12 when I got addicted to Star Trek in the fall/winter of 1975. My personal "SF Golden Age" came along later, though, during my bookhunting years. Every Saturday was when I'd make the rounds of every bookstore, book stand, the Farmer's Market, and promising garage sales to find those elusive science fiction books by my favorite authors. Back then I was in junior high/high school, and an expensive book for me was around $2.00. A super-expensive one was an
Alfred Hitchcock and The Three Investigators hardcover, which cost $3.49.
To a kid who was babysitting for 50 cents/hour, and didn't get an allowance (my grandparents didn't believe in allowances, though they'd give me money for a special occasion such as a day of rides at the fair), it was a tough decision sometimes, whether to get a 45-cent second-hand book or splurge on the 95-cent new book. I remember my mother just about throwing a fit when she saw me counting out 7 quarters (over 3 hours' babysitting wages) to pay for
Spock, Messiah!. But then she a) didn't understand science fiction; and b) couldn't fathom why anyone would spend money for a book.
(I still have that book, and aside from the notes I made on the inside cover, it's in perfect condition. I bought it on September 16, 1976, at the Hudson's Bay store - and noted that it was the 26th Star Trek book I'd bought.)
The 90's. ... When Disney was at it's best.
Okay. I will admit I liked Toy Story 2 (saw it on December 30, 1999). But Disney was at its best before all those ridiculous remakes of movies that didn't need to be remade.
I'm going to answer 1975 - 1985. 1975 was the year I got into Star Trek and my life took an abrupt turn off the path it probably would have taken. This decade was most of junior high, all of senior high, and college. It was the decade when I started working in theatre and going to science fiction conventions (meeting authors, not actors).
Maybe I should have clarified which Disney movies were the highlights of my young life instead: TLM, BATB, Aladdin, The Lion King, Hercules, Mulan, Tarzan... I also loved The Emperor's New Goove and Lilo And Stitch but they were early 2000's.
I never liked Toy Story.
Sorry, I don't speak alphabet soup. I have no idea what "TLM" and "BATB" mean.
Disney movies, to me, are the classic animated ones such as
Snow White,
Sleeping Beauty,
Cinderella,
The Aristocats, and
Lady and the Tramp. For live action ones, my favorites included those in which Dean Jones (RIP) and Kurt Russell played the leads.
