well I disagree that you need to research this movie before you watch it. So I'm confused as to why he said that
You absolutely don't need to.
It's amazing, I NEVER heard this level of criticisms of the easter eggs and set ups in films like Thor, and Captain America:The First Avenger, etc.
I mean, sure, Iron Man 2 AOU got a lot of criticism for being largely to set up the further installments, though I disagree with some of the AOU criticisms.
Marvel's films are FULL of unexplained elements and tie-ins that, if you're in the know, flush out the story, and if you're not, sometimes payoff later, sometimes they don't.
The delineation between TV and Film is all but gone (I'm not talking about cross platform universes, but story telling wise) and people praise it all the time, especially on the TV side.
But now BvS is getting ripped for every thing in it that could possibly be furthering a larger, on going plot.
God forbid they show anything indicating something ELSE might happen in a franchise we already know IS happening.
We love the crap out of that when they do in during a TV season.
That's something that really stood out with DD season 2 for me, vs season 1. While season 1 did begin laying the ground work for the Hand, and season 2, it was much more it's own complete story than the usual tv season. Which was great, don't get me wrong, there's nothing wrong with this in TV, and it's part of the vanishing delineation I was speaking of.
But season 2 started doing a lot more long form set up, I found, and we praise the **** out of it on TV, and print comic book story telling.
I LOVE that we are finally seeing this done more in film, and we're seeing it done better and better.
It's very much a new thing in the cinematic language. Yeah, there's always been sequel set ups in films, or following up on things that happened in earlier films, but they were always an after thought.
We have entered a new cinematic era in terms of how stories are told on the silver screen.
There are, will be, and have been, stumbling along the way, clumsy execution both due to learning, and rushing, *cough* Iron Man 2 *cough*.
But films like BvS, and even AoU are actually doing a pretty decent job with expanding, and including, this kind of, traditionally television based, storytelling.
This is not indicative of needing to research these elements before hand, same as you didn't need to research the Hand, Stick, or "Black Sky" (something not even from the books, but introduced in the same long term story telling way) to understand DD season 1.
These are things you (meaning the GA) are going to learn about by watching the movieS. That IS the research.
