Review of H2O: Just Add Water

I used to watch this show as a kid and I loved it. The effects were good and are still decent today, the tails were beautifully designed if you watch the behind the scenes videos. However, the characters didn't seem all that realistic, the acting was decent but I'll give it credit for covering important subjects like animal abuse with illegal fishing of sea turtles etc. This show does have some substance and morals that are interesting but besides that it's dull. The underwater scenes are beautiful to look at, although there are some aspects that I just can't overlook. First of all the title is incredibly stupid. H20 just add water doesn't make any sense, if you replace H20 with water, the title literally means water just add water! H20 is just the chemical name for water which is made up of two hydrogens and 1 oxygen= water. There are a few plot holes and stupid moments that make no semblance of sense. ( spoiler alert) How Lewis first tests the water inside of the girl's DNA. It is not scientifically possible for a person to have a mermaid's tail just by swimming in a "moon pool" there has to be an already existing genetic material from some line of lineage. So, he should've tested the girl's DNA first and then the water to see what activated the genetics. They do explain some of this when Charlotte shows up in season 2-3 but besides that it should've been obvious. It is an enjoyable show for kids but lacks in certain parts.
