It’s one of the best-loved movie trilogies, but with such a complex time travel narrative, there were always going to be some plot holes, right? A new fan theory argues that Back to the Future Part III was totally unnecessary and that Doc and Marty could have quite easily returned to 1985. It all comes down to the DeLorean in the mineshaft apparently.
Remember at the end of Back to the Future Part II when Doc was struck by lightning and sent back to 1885?
Well, he buried the DeLorean in a mineshaft to be uncovered by his younger self and Marty in 1955 so the latter could return to 1985.
And yet the young time traveller decided to go back to 1885 to collect Doc anyway.
But when he arrived in the Wild West, Indians shot the DeLorean’s fuel tank so the two were stuck, with Doc set to be shot by Biff’s ancestor on the following Monday.

In the end, the pair decided to push the DeLorean up to 88 mph by hijacking a steam train.

They wrote: “There were two Deloreans in 1885 that Doc and Marty could have used to make one functional time machine and return to the future, after rescuing Miss Clara of course.
“Let me start by quoting Doc (roughly) about how timelines work. Remember the drawing he made for Marty?”
