I don't find trailers spoil anything for me. I love watching trailers and getting a 'sense' of the film. The majority of them don't spoil the movie... in fact the only time I can think of where I felt like a trailer did was Cabin in the Woods. I literally immediatley wished I hadn't watched that.
I just wanna avoid major story details.
But TBH... I doubt i'll succeed.
It's like any addiction. You think 'oh readind this ONE spoiler won't do too much damage'... and then again... and again... and it all adds up
'Why do I find all of this so horrible to explore?
Sure, they are interesting questions that I don't mind seeing in an elseworlds GN. But as a theme for the film that is kicking off the tone of the whole JL, and in a film that is presenting Superman to the general audience in a way that current generations will remember him?
I just don't like it. It's dark, it's depressing and it's not how I like the tone of Superman films to be.'
