I was wondering how similar Michael Dorn's introduction on DS9 was to Jeri Ryan's on VOY. In both cases the writers/producers decided to bring in a new regular character in the fourth season to boost the ratings and rejuvenate the series. With DS9, they went with a popular, big-name character from a previous series, whereas on VOY they brought in a "babe" to boost sex-appeal. I've heard there was tension on the set when Ryan came to VOY--some of the other actors were jealous that this newcomer was stealing the spotlight and getting all of the attention. Was there similar tension when Dorn came to DS9? And did bringing Worf back work? Supposedly Seven really did boost VOY's ratings and saved the show--did Worf do the same for DS9?
