WAY Better than SPLASH
25 September 2010 | by (United States) – See all my reviews

This is the BEST new show I've seen in many years, and I've been watching television since 1966. The effects are superb, the actors are both very attractive and very talented. And the Australian accents make it all the more adorable. "MERMAID" just sounds SO much better when it rolls off the tongue of a beautiful Australian actress. You have to watch this show from the start, and give it until season 2 to really hit its stride. It gets very humorous in season 2 - truly a joy to watch. Great for all ages - trust me on this one - i know my mermaids! If this show had an advertising budget behind it it would have been a super smash. Oh and yes I agree - the music is also excellent especially the theme song NO ORDINARY GIRL. I just LOVE this show! If you only watch ONE EPISODE - be sure its SEASON 2 episode 15 IRRESISTIBLE. This is by far the funniest of all the episodes, some of the humor will be lost on you if you haven't seen the prior shows, but it can stand on its own just fine. I'm off to roll around in some ambergris and shamelessly throw myself at the cast...
