Great show. But one problem, there have been times (mainly somewhere in Season 2) that there is way too much teen drama. Wish they could lower it down a bit. Besides that, the show was awesome.

I love this show it's the best they need to make more seasons where they are all grown up and they have the same boyfriends and they are married and they have kids and they don't want there kids to know they are mermaids till one day they do and it's all still one big secret. This is what I think they rest if the seasons should be if you have something else just comment and tell we can all share our stories of what we want cause if the directors see this it could be more shows on it and we might get lucky and our parts of things we think could be in the show all I want is more seasons I think everyone does !!!!!😁😁😍😍😍
