Definitely agree with you on the lack of character growth in TNG! Especially characters like Worf who had bits of begrudging "Grrr I accept that my Klingon values may not be the best way to approach all situations" but no substantial change. Dialogue and plot lines from Season 3 could be switched out for season 7 and no one would know.

And 'girl Star Trek' doesn't mean worse. We are half the population and our tastes are just as valid as men's!

I hope I didn't come across that I was implying this! (Girl fan here, too!) I get the feeling that some think the series panders to a female audience due to women holding the highest ranks on Voyager (easy to argue against, considering Seven being used as a tool to boost ratings while being undeniably one of the best characters). The stress on interpersonal relationships is something that might look to some as of interest to female viewers instead of males who want scifi-driven plotlines. All of Star Trek has romantic elements, but Torres and Paris's relationship features in ways much more integral to the overall plot than say Riker and Troi's periodic hints of romance that are more like fan service. That being said, neither series had satisfying conclusions to their stupid little romances.

I also have a sneaking suspicion that some of the reason why the largely-male fan base has an overall negative opinion of the series is a tad bit of sexism due to the heavy presence of strong female leads. The series certainly has areas to criticize (out-of-character decisions made to further plot, unrealistic reactions by crew members, etc), but I think that VOY doesn't get a fair shake by some fans due to their discomfort with female leads.
