I mean, I don't see why it's hard to understand why someone wouldn't want to go in blind for a DCEU movie at this point. And by that logic, then uhh, you shouldn't really bother with seeking out impressions then either if someone really cared that much about not being influenced.
If they announce a new Batman, Xmen, Spiderman, etc., you know instantly if it's something you want to see and you're probably going to eventually see it, so instead of spending hours reading about it, just use that time to see it instead.
Eta- look, you all are going to watch this movie regardless of the reviews. The soone you realize this, the more fun you'll have.
