... because the franchise is so successful?

Not really sure why some people think a thriving franchise needs a reboot.

I wish they would just stop making the films, because they boring and I'd rather the studios focus on making actual great cinema. However, if they don't stop making them, I hope they cast a black, Gay Bond who sleeps with lots of white men, just to f^ck with all the bigots.

They tend to reboot it with every new Bond. If Tom Hardy is Bond (as is being predicted now) then I would say the franchise can remain more or less the same though, as I would guess he would play a similar type of Bond to Craig and in that case there would be no need for a reboot. I don't think he should play Bond though.

Every Bond actor has a shelf life of 8-10 years. Craig is actually one of the longest alongwith Moore. Since Specter is the first of a two-part story, it's sequel will definitely be Craig's last.

They should reboot the series with a duck, that way they can have a Bond who likes to dig his head in, out of frustration, right!
