Any H2O fan willing to produce a dedicated blog on the show is entitled to an opinion of having a Season 4.
How can we not have a Season 4? The show is not complete.
For one, we still have four active mermaids. To the best of our knowledge, Emma is still a mermaid. None of them have permanently ended being mermaids.
Furthermore, none of them are married yet, so all of the romantic subplots remain active. It may be clear that Lewis and Cleo are a couple to stay, as are Will and Isabella (and let's keep it that way), but the whopping cliffhanger of Season 3 is Zane and Rikki. And I've got my own story ideas for how that should play out.
Now some might say that saving the earth at the climax of Season 3 is the pinnacle of their mermaid careers, and the very purpose and calling of them being mermaids. In the first episode, Emma said, "and we certainly don't know why." Well now we do. But there is more to do, and more situations for our girls to muddle through.
