I pick the Bond series because it's more realistic than most on that list, it ran for a much longer period and is still running, and I cannot remember anyone of the films being a failure since it started somewhere in the sixties. It also has a more general and bigger audience and it is an excellent series. Yes, I am sure Bond is the best and longest running movie series of all times.
I think i like Fast and Furious series. Because I like action. And the entire cast of the series is my favorite.
