A good time travelling film

Rating: 10/10 (15 December 2018)

The first films said you shouldn't change the past or the future, and it was good after the events of the first two films that Doc wants to destroy the time machine.
Marty instead going back in time to save Doc showed his loyalty to his friend, and having the 1955 Doc help him was a good time traveling twist.
Clara was a good twist, considering the first film you'd assume that removing someone from thier own time could unpredictability affect the timeline but the fact that Clara, on the moment of her appearance on screen, should have died meant she could leave her time with no effect on the timeline.
As before why are the years always in multiples of five? 1985, 1955, 2015 now 1885. There are other years.
Despite the destruction of the time machine, Doc's new steam engine time machine, together with Doc and Clara's children, give them the potential for a fourth sequel.
And the fact that they named the children Jules and Verne (after thier parents' favourite author) could hint at a potential storyline wherein, to exploit the timeline for thier own gain, the boys could sell Jule Verne's novels (combing thier names to become the author thier parents love)
