I had very high hopes for this series after watching the min-series upon which it is supposedly based, but these proved to be entirely on the wrong side of the map. The actors were completely unsuited to the roles, the stories were ridiculous, cliched, and embarrassing to watch, and the decision to use the same characters as the mini-series with a new cast had disasterous and distracting effects.
The 'fairy-tale' feel of the mini-series was not present at all. The dinotopians spoke with american accents and used modern slang and language; instead of 'certainly' or 'yes sir', everyone said 'sure'. Most people seemed to use words like 'babe' on a regular basis. The ideals presented in the miniseries, along with facts of life and about the island, were ignored and misrepresented. The series sees the introduction of a Xena, warrior princess-style villainess, who lives in a castle with her american crossbow wielding henchmen. In only the third episode a man invents an elixir of life and magically turns into a child. The whole thing is utterly, mind bogglingly ridiculous.
To summarize: The scripts were obviously written by unskilled, poorly paid authors, the starring actors were not very good, the magic was gone, the extras couldn't act for toffee, and the storylines were ridiculous and not at all in keeping with either the mini-series or with the books. It isn't even good for a laugh. It may entertain sex-obsessed cheap-thrill loving americans, but it doesn't entertain me.
