Really unique tv series made in Australia in 2006 year. H2o - Season 1 is a 5/5 tv series for me. These days, fresh tv series coming to the cinemas, do not have 'something' what this tv series has. H2o - Season 1 is definitely the type of tv series that you can watch several times and always see something new, interesting. I didn't notice anything wrong in H2o - Season 1. You don't have to be fan of Adventure, I'm not too.
