You hit that nail on the head. Jack Bauer has saved the Nation how many times now? For what does he need Redemption?
This was the flaw inherent in Mad Max Beyond Thunderdome, which made it a truly terrible movie. Max was a great hero, and needed to apologize for nothing. But to the Hollywood mindset, he wasn’t great until he helped save some poor widdle kids. It killed the whole concept.
This will kill “24”.
