There is no singular reason why everyone goes to the theatre. Some people go so they have something to complain about. Some people go so they can then state their opinions on EVERYTHING. (Ever been to a talkback? If you have, you know who I am talking about.) Some people never see the forest for the trees. Some people go so they can make lists. Some people make those lists in the form of questions.
The above are not questions; they are answers. Perhaps they counterbalance some questions a bit. Anyone is free to ask whatever they want. Anyone is free to provide answers (whether to questions that have been asked or otherwise.
Personally I find that sometimes it is better just to let someone blow off steam.
