This is a list of those who I love, enjoy, and hate on 24! This is a very comprehensive list, from season 1 to season 6 of all the people that I care to mention and some aren’t mentioned because they aren’t worth mentioning.
Love:

Those who I adore in 24!

• Jack Bauer
• Tony Almeda
• Michelle Dessler
• Chloe O’Brian (She is the CTU Analyst that supported Jack no matter whats the consequence, and she wouldn’t take crap from anyone no matter who they were)
• Edgar Stiles (He was an extremely good Analyst as well, and he stuck his neck out a few times in his querky way, I was saddened that he died)
• Milo Pressman (Another analyst thats smart and he helps Jack out when he can, good guy!)
• Morrison O Brian (He is a the sarcastic british analyst who I can’t get enough of, smart and funny, always finds a way around)
• David Palmer (A great man who always supported Jack, and gave him the necessary power!)
• Aaron Pierce (Secret Service, protecting David Palmet and up until Season 5, a great man)
• Wayne Palmer (The Brother of David Palmer, he proves himself! Great Guy)
• James Heller (Secretary of Defense in Season 4, he supported Jack and employed him)
• Audrie Heller Raines (She worked for her father, and also fell in love with Jack, and Jack loved her, she cared for Jack)
• Paul Raines (Season 4, He was a bit of prick, seperated from Audrie, but later on proved himself to help Jack a lot)
• Bill Buchanan (He was in an administrative position but always putting his neck out for Jack, so he’s got my vote!)
• Curtis Manning (Tactical Head at CTU, he helped Jack in lots of situations and he was put in some tough situations)
• Habib Marwan (He was an extremely intelligent terrorist who is the bad guy you love, he was acceptable to being Jack’s enemy)

Enjoyed:

Those who make 24 interesting!

• George Mason (Season 1 – 3, Sometimes hindered Jack but helped in the end.)
• Ryan Chapelle (Season 1- 3, he was an annoyance to Jack, but his end is what won me over)
• Mike Novik (President Palmer’s assistant)
• Kim Bauer (She was good sometimes, but I think the show is better without her, her side stories were very annoying after a while.)
• Kate Warner (Victim in Season 2 that works with Jack)
• Chase Edmunds (Jack’s Partner)
• Tom Baker (Swat guy that supports Jack!!)
• Ramon Salazar (Season 3, They were the ones who were getting the virus and between the two Salazars they were an interesting combination)
• Hector Salazar (Season 3, The angrier one of the brother)
• Claudia (Season 3, She fell for Jack Bauer from the Salazars just like every women should)
• Stephen Saunders (The other bad guy from Season 3, he was a cool English bad guy, I liked him)
• Behrooz Araz (The poor young persian guy who was almost killed by his father, and even after helping CTU he was taken by the terrorists, poor guy was really screwed!)
• Lynn McGill (He was the guy who came from the head office trying to run CTU on Season 5 trying to push Buchanan aside, it was funny seeing them handle him, he was annoying but at the end he was ok.)
• Cheng Zhi (He was the guy from the Chinese consulat that was chasing after Jack, it made things interesting)

Hate:

• John Logan (I hated the bastard in season 4 as Vice President and Season 5 as President! He was an ass and desereves to die!)
