As a general rule, when you are a vampire slayer... you shouldn't fall in love with a vampire. Not least because it might affect the dynamic of your TV show and have your viewers turning off. But fall for Angel, Buffy did and it was something special!

Never before have a tv audience so wanted an onscreen romance for so long as was the case with these two. From the pilot episode when we were introduced to Mulder (the out-there FBI agent that believed in UFO) and his new partner Scully (rational analyst assigned to discredit his outlandish theories) there was chemistry.

Can friends ever be successful lovers? This on again, off again romance played out over most of Friends' ten seasons and asked that very question. They had plenty of great moments... and twists. Rachel was Ross' dream girl that he couldn't get out of his head...even while he was saying his marriage vows to another woman.

From the very first episode this was going to be very special. Addison was a wiseass slacker private eye with a razor sharp wit; Maddie was a former fashion model turned businesswoman with an excellent delivery of sarcastic retorts.

They say opposites attract. So when serial misogynist, former baseball player and bar owner Sam Malone met the very prim and well spoken Diane - it was pistols at dawn. Their constant arguments and tit-for-tat insults fanned the flames of arguable TV's greatest ever sitcom.
