Season 5 is definitely a nail-biter and generally considered to be the best season. It’s also the season that walked away with all those Emmys. Best drama, best actor, etc. Though it’s hard to tell whether it won all those Emmys because the voting committee really thought it was the best season, or whether it was simply because by that point the show had become a major critical and commercial hit. I’m also a big fan of season 4 because that was the season that hooked me. It also sets things up really nicely for season 5, including the introduction of many new characters (Bill, Edgar, Audrey, Secretary Heller, Walt Cummings, and especially Charles Logan!).

It’s a tough call to pick my personal favorite. I’m a huge fan of seasons 1 and 2 because that’s where it all began, with all the great characters like David Palmer, Mike Novick, Aaron Pierce, George Mason, Tony, Michelle, Nina Meyers, and who can forget Sherry Palmer???

But season 5 is also up there. So it’s a tough call.
