I'm starting to suspect this is how non-Firefly Fans felt when trying to talk about Serenity with Brown Coats.
I asked a simple question, and true I didn't specify, but it was kind of directed at people that, you know, have actually seen the movie and could answer my question.
You're question was does a sequel movie have spoilers for the show that came before it. The answer is "Duh", I don't need to watch the movie to know that. So don't give me attitude because you asked such a stupid question.
It might interest you to know that I did skip the movie, at least until I'm finished with the show. I had a chat with a friend who convinced me that the movie would spoil the show. And oh yeah, he was much more polite about it than you were. It's called tact, look it up.
