I'm pretty sure it was Bobby Ewing who turned out not to be dead at the end of the season, whereas JR was really shot (just not killed). However my memories of 1980s soaps are somewhat hazy, like most people here I was more interested in things like Z80/6502 assembly code than big-haired women catfighting in ludicrous shoulder pads [0].

However, genuine thanks for the Lost finale spoiler, I never wanted to watch beyond season 2 anyway as it already became rather tedious.
