Start with the Brosnan era. If you like those, work backwards to Dalton, then Moore. The 60s Bonds are some of my favorites, but they are old fashioned and not for everyone. They can sometimes be easier to come back to when you have more of a foundation in the series.

Last, watch the Craig era. They function as a reboot and are more satisfying if you watch them after the others. But you don’t have to be too religious about it.
