That is something that also annoys me (although I also post boxoffice numbers and discuss boxoffice for certain movies).
For new movies in theatres (especially prominent ones) there would be the possibility to make three different threads:
XYZ reviews/discussion without any spoiler
XYZ reviews/discussion with spoiler
XYZ boxoffice
for Web or smaller films, I think, it's okay to integrate boxoffice into the review threads
The other point that verdicts are - far too often - a discussion point...well, as you mention, it could be a lack of knowledge...
I bet, there are members here who join a discussion about a movie they even haven't watched only to bash it (or a certain actor/actress)
I think it's up to us to react to them accordingly...it's not the moderators' or the admin's task.
