My favourite tv ships are:
Mulder and Scully (obv)
Luke and Lorelai from Gilmore Girls, i was so pleased when they got together and just as gutted when they split up.
Ok i know its a miniseries but Jack and Aliena from Pillars of the Earth.
Xena and Gabrielle from Xena, who IMHO had sexual tension to rival Mulder and Scully. I really wanted to see these two get together and have a relationship but alas it was never meant to be
The Doctor and Rose from Doctor Who, i just loved them.
