Hi, I'm a fan of 24, watched season 1-6, some of them several times. Season 6 is currently in german TV and I really like the show. I will watch season 7 just as curious and captivated as the previous 6 ones, but I have to say that I'm also a little bit bored of it. I think there are too many repititions (I'm mainly talking of Season 6, previous ones are not absolutely present in my memory..): Traitors inside of the CTU, conflicts between CTU-Agents, The good ones forced to trust untrustworthy people, and of course the heroic Jack Bauer who has to break some laws to succeed and in the end saves everyone. I mean, some things make sense to repeat and it's still a very exciting show, but these things just annoy me.
Maybe 6 seasons were already too much. I think (although I like him) it might be time to replace Jack Bauer. It's a tricky thing, I know, but as often as he got rehired as an agent... Come on, this gets ridiculous!
