I've re-watched the whole West Wing series thanks to netflix. The last two seasons were different because the emphasis was on the Santos campaign. Jimmy Smits for president--yes pleeease!!! ;-)
The earlier seasons had subtitles in English and since Bill and I always like to watch things with subtitles I got very used to them. The later seasons dropped the English subtitles for some reason and only have them in French and Spanish. My French is better than my Spanish and I like seeing how they translate - often very America-specific - words and concepts. I like to think that watching it this way is also improving my French vocab a bit too.
