You can't go wrong with the Sean Connery/Roger Moore era Bond movies. Pierce Brosnan wasn't that bad of a Bond either. Haven't seen the latest movies with Daniel Craig yet.
I have to agree with Ernie. Sean Connery and Roger Moore = Founding characters.
Pierce Brosnan, in my opinion was more GQ than Spy. It becomes more and more unrealistic with Daniel Craig era.
The Last bond movie I Saw about the Poker Tournament, I had to LOL when he he was having a heart attack, or something, and he ran to his car and sure enough, what was in the glove box? A whole defibrillator, with paddles and all. Thats when I kinda said, pfft, to the whole secret agent man.
