Aren’t the trailers and teasers massive spoilers ?

This applies to the live-action only audience, but aren’t the promotional materials spoiling the content too much? As someone who has watched the anime, of course I know what’s coming but if I was a first timer, I would be kind of annoyed with the extensive sneak peaks into the season.

Does this bother other OPLA only watchers?

I don’t know, I was expecting some level of mystery being maintained. Or is it that the show is more in favour of throwing Easter eggs and references for a more familiar audience?
