A great film let down by a major plot hole

Rating: 7/10 (21 October 2008)

This film had a lot to live up to after th 10 out of 10 first an second installments, and it nearly hits the nail on the head, except for one thing...
Why the hell didn't they use the petrol out of the delorean that Doc Browne arrived in to fuel the delorean that Marty arrived in that had the fuel leak out of it?? I'm sorry but a plot hole like that cant be explained away. If you can explain that plot hole I'd be grateful cause I want to rate this film 10 out of 10 cause otherwise it is great. Tannen once again is brilliant and how can you not like doc brown? Its a shame they never mentioned how Marty and Doc Browne met though but thats only a small thing.
