I guess she did like the wholesome types, Mal (Nathan Fillion) and Jack O'neil (Richard Dean Anderson) from MacGyver/Stargate were her favs. I forgot about the 'companion', she was Beautiful, that didn't stop Mal treating her badly on occassions, obviously had some issues with her 'occupation'.
Doc and his Sis were definetly odd, but as you said, that's why they were there. I watched a documentary on Firefly which mentioned she did her own fight stunts, apparently she had done ballet etc for years and could kick high and fast {eek3} Usually when you see young females beating up large men on films it stretches the credulity, but I think one of her boots hard and fast against the head or jaw would knock most guys down.
Halo is worth chasing up, the series veared a lot from the Halo 'cannon', which upset some hardcore Halo fans, but I didn't mind the changes, maybe I'm getting brainwashed by the 'message' {eek3} ^&grin I really liked the Halo game, possibly more than both sons. I'm a full on First Person Shooter type of player whereas both sons prefer adventure based where they have to find things and solve some mystery. At least once a year we do an Escape Room adventure in Brisbane, Queensland. Not sure if many TF members have heard of such a thing but have found the WW2 themed rooms a lot of fun. We recently saved the UK from assasination attempts on their WW2 PM and V2 missile attacks ha ha. But have to say, they do require some serious 'thinking' to succeed, they're only for Nerdy types I'd say.
