I started to watch Millenium when it first aired, but never liked it. Although I agree, it shows some X-Files influence. I never thought the portrayal of Mulder watching porn was sad. After all he is obsessed with his work and has practically no private life, no romantic relationship ... and obviously no sex life. Under this circumstances I'm not surprised that they made the character watch porn. As strange as it may seem, I always thought it would be fitting.
