BSG hasn't fared too well outside of Grace Park. Tricia Helfer's score wouldn't have been good enough for the 2008 and 2009 tournaments, and Katee Sackhoff was panned. Mary McDonnell was actually rejected by some people even though she was never considered!
Of the Trek actors, Jolene Blalock and Linda Park were panned, Zoe Saldana scored well but didn't qualify, and Jeri Ryan was highly rated but didn't last very long in the tournament.
Firefly is the anomaly, with a weak 2008 final four that was half Firefly (though the weakness was more Staite than Glau).
