The Total Drama series

Does this ever explain the show's quality in each season?

I don't see any big trends here. I think whatever issues they have are related to the writers' room itself and Executive Meddling.

Good news, we finally have a release date for the first season of Island 2023 premiering in the US on June 1st.
