Okay, what we've done now is that we've created new threads for the last two movies.
This way, within the thread for Movie 3, you don't have to use spoilers when discussing Movie 3 (but you should still consider it if revealing major plot points as a courtesy). You may also use the Movie 4 thread to discuss your speculation for that movie.
Hopefully that should address some of the different perspectives in this thread and remove some of the tension about what is and isn't a spoiler.
This thread is re-opened now to focus on the first two movies.
