I bought the complete James Bond DVD collection a few months ago and for 2006 have decided to view them in order, one every Friday night, for the next half year. I started, of course, with Dr. No. It holds up very well. I remember seeing it as a kid in our town's single theater. Nothing could be more of a religious experience than seeing Ursula Andress rise from the Jamaican waters. There's a certain claustrophic feel to the nuclear core scene that later films, with larger budgets and sets, did not possess.
I'm looking forward to seeing the rest of the films, especially my favorites, such as Goldfinger and You Only Live Twice. I'll keep you informed of any insights I might have with a 40-year retrospective.
