for the bad entries its out of nostalgia. Bond films been around for 50 years plus, that's long enough that every man under 90 has some likely positive memory of the Bondster at some point in his youth.
I could go the rest of my life without ever seeing A View to a Kill Again, but From Russia With Love? Sheeeit man, uncomfortable colonial/racist/sexist overtones and all, classic Bond is good fun.
