7. Sabrina The Teenage Witch
http://www.youtube.com/watch?v=wL6pCdpNPNI Over 17 million teenagers were wowed by the first episode of Sabrina the Teenage Witch; it was a show that captivated an age group for seven years, spawned three movies, and probably sold more dolls than any other TV show of its era. So why on Earth did the theme tune sound like it belonged to a bad game show? The key-shifting, guitar-squealing abomination sounded a cross between Stars In Their Eyes and The Generation Game; all that was missing was the cheesy voiceover, announcing that anyone in the studio audience could walk away with a prize. The awful theme was coupled with a boring title sequence that used what looked like WordArt for the actors' names; glittery chimes were sprinkled over the girly pop-punk, before a few notes of 80s keyboard at the end. It was a mess of a theme tune: it's a wonder so many left the show on after such a terrible sequence. Sabrina would later have another two theme tunes, neither of them that much more exciting, but the last one offering lazy lyrics. The theme song probably wasn't a catalyst in the show's cancellation, but whoever composed it should be ashamed of themselves.
