I saw Spider-Man: No Way Home tonight. The no spoiler ban has been lifted. THat being said, if you know someone has not seen it, or is unable to see it for various reasons, DO NOT spoil it for them. Because at this point, you are a big jerk. Some people aren't lucky enough like we were.
So please, be kind, and keep the spoilers between people who have seen the movie. It may not be much to you, but it is to others.
