I liked that ending better when it was called season 4. Eh, it wasn't horrible, but it just wasn't finale material either. It existed for the sole purpose of setting up movies. Every important character is still in play, even if Logan might actually be dumb now like he pretended to be back in season 5. The only character who actually had any major downfall in the end was President Taylor, but no one really cared about her anyway. I really enjoyed the first hour and a half last night, but the last half hour was a bit of a let down. And I don't know who is at fault on this one, but not having Aaron Pierce at any point in this season was a major disservice (don't know if it's a word, but it is now) to the hardcore fans.
On another note, whatever political party Logan and Taylor are from is pretty much screwed in the 24 world. Keeler is elected and then shot down in air force one. Logan then takes over and is forced to resign. Then no one knows what really happened with Hal Gardner. Anyway, a couple years later, Taylor's elected but eventually resigns after major scandal. There's no way I'm voting for the next guy.
