It's not about what crazier, it's what makes sense for the film. The film can do whatever it wants as long as it sets the rules and sticks to em. Those rules can't change when it's convenient for the plot. (i.e. Clarifying that you can only make 1 wish - but allowing Barbara a 2nd because of "generosity") It's a consistent issue throughout the film.
When the title highlights "84" and marketing stresses all the 80s nostalgia - you gotta dip the toes in a lot more than what they did. Ultimately, the time it took place meant nothing. They could've done a lot more with the Cold War and other early 80s callbacks but instead was just used for Steve's fish out of water clothing montage. Anything else that was featured in the film could have taken place in any other timeframe and it wouldn't have made a difference.
Well, whaddya know...
I wasn't big on DC as Marvel (except Batman) so I'm in the dark for most of that stuff.
