Her accent was supposed to be "alien and exotic." I could have accepted that until Majel Barrett showed up. They tried to tapdance around it by having some reference to "I see you still haven't lost your accent"... which would imply that she got it from her father. But in the next season, his name sounds fairly North European. So where the hell
did she get that goofy accent in-universe?
But comparing Season 1 to Season 7 (and beyond, when she appeared on Voyager and in the movies), I actually do prefer the earlier seasons. Her draaaawwwwled-out, slaaawpy accent later on just really grated on my ears.
Disagree with Diana Muldaur and Whoopi Goldberg.
Diana Muldaur played a character who was Picard's equal in a lot of ways, and took no crap from him. I didn't like her bigotry toward Data, but she did make an effort to overcome that. I wish she'd stayed. I really did not like Gates McFadden/Beverly, as her only real reason to be on the show was this continual question of "Is Picard Wesley's real father?".
And Whoopi Goldberg was just plain fun as Guinan. A friend once hosted the TNG version of the "How to Host a Murder Mystery" dinner/role-playing game. I was given the role of Guinan "because you have weird hats in your costume collection." We had a great meal and solving the mystery was a lot of fun.
Some time before TNG was offered to him, he was in a production of Hamlet with Lalla Ward (she was on hiatus from Doctor Who) and asked her how she could stand doing a TV series instead of acting on stage. Fast-forward to 1986 (or thereabouts; not sure when he was cast in TNG), and he took the job because he honestly expected it to last a year at most, if not be cancelled after 13 weeks. He never expected it to last 7 years plus movies.
I've only seen her in one other thing - a really bad TV-movie. I don't even remember the name of it. Frakes was in some miniseries... North and South? His wife, Genie Francis, is currently on General Hospital as Laura (the actor who played Luke retired a couple of years ago).
As a twin sister?
She would have been a lot better than that stiffer-than-cardboard "actress" they did get. I remember her from Dallas, in which she played Carter MacKay's daughter and was a brief love interest for Bobby. She couldn't act worth a damn in that show, either.
Not to worry. Fanfiction has provided.
