10 Entire Movie Plots That Were A Waste Of Time
9. Back To The Future Part III
Time travel is a tricky business, and it's rare to find an instance where an audience isn't able to pick holes in it.
Each installment of the Back to the Future trilogy has its own problems, but one that is less widely talked about is the issue with the third movie that would have ended the story almost as soon as it had begun.
Stuck in 1955, Marty McFly employs the help of young Doc Brown (again) to try to return him home. The pair discover that 1985's Doc Brown has travelled back to 1885 where he has settled and made a life for himself, and that he buried the time machine in an abandoned mine for the pair to find in 1955.
Marty travels to 1885 to rescue his friend, only to have the time machine's fuel tank destroyed upon arrival, leading the pair to use a steam train to push the time machine in the hopes of achieving its required 88mph to allow them to travel back to the future.
Why didn't they just dig up the machine that Brown had just buried, use the parts from the repaired version that Marty had just brought back, and travel back immediately?
Sure, we would have lost out on Marty inventing the Frisbee and the bulletproof vest, but it would have made much more sense.
