Members have the right to post there views about series they like and don't like. As long as the post follows the rules there is no set rule saying you "must like said show to post in this thread." Obviously when someone crosses the line into flaming, baiting and what not that
is against the rules then a mod will step in. This is why we have a
Report button since mods can't be everywhere.
If you don't like someone's repeated opinion on a show, we also have the
Ignore feature.
This is a discussion community. All types of discussion are welcome, positive and negative again as long as it follows the rules. Banning any type of negative discussion wouldn't progress this community since it's part of life. If you don't like it, again use the ignore feature. If you think it goes beyond whats allowed, report it and let the mods handle it.
