The best way is to create a content report using the report function, for example for a TV-series. One report is enough, just make sure to include information about which episodes are wrong and why. Then a moderator will take a look and decide what action is needed, and eventually the episodes will be deleted.

If the moderator does not respond to the defect report for long time, how should we do? Is there no way to correct the contents? Actually, (at least) some defect reports have not received any responses for over six months.

Hi Sportacus, can you link to one such report? If a report is more than 2 months old bumping is allowed.

Thanks. TV is not my domain, but feel free to bump one of those reports (one report would have been enough since it's just one question). I would also check the TV bible to see what the current rules say about such an entry. Finally I would take a look to see how similar entries have been added previously on TMDb. But a bump could hopefully get the attention of one of the TV-mods.

There is no need to post here. Your report will be processed. It may be processed quicker if you add to it an official proof that the series was cancelled.
