I'm still baffled as to why people continue to think the series finale would be different than any other episode on the show.
Probably because the entire series was one big promise of a decent payout in the end. It was supposed
to be the story of Clark Kent growing and becoming Superman. We didn't even get to hear the name
of Superman in the end.
The show teased the audience until the bitter end and didn't give anything close to a payoff after ten years of said teasing. That's
what pissed people off.
