The show really changed it's gears...
The show in it's earlier seasons could be frightening at times with creepy tones (especially the 2002 season). But also had convincing romances, scandals and complex characters with some silliness thrown in too.
Then by about 2003 the show started to change its tone. By the later seasons it became overly silly with shallow characters, highly unconvincing relationships and all previous elements of ''horror'' in the show were removed. The show just died after that. What a shame.
