Stupid plot altogether

Rating: 5/10 (1 April 2019)

So to start: What was Doc's hurry to bring Marty to 2015? They could've taken months to devise a real plan, WITHOUT BRINGING JENNIFER. They had a time machine for god's sake. Second: why did they go all the way back to 1955 to retrieve the almanac from Biff. Just go back to 2015 an hour before Marty bought the almanac and either stop the purchase or buy it and burn it then. So you say, "It's a different, altered 2015 by then, so they can't." If it's THAT different then Biff never could take the almanac back to give it to younger Biff in 1955, so that alternate timeline could not exist. And Doc makes such a big deal about someone interacting with their past/future selves. Well, Biff gave himself (in 1955) the almanac and explained what it would mean to younger-self Biff. Nothing bad happened with that scenario. Or go back to 1955 a day earlier than they did, slash Biff's tires or otherwise hinder the meeting with his older self. They have a TIME MACHINE! If one plan fails, go back and try again. Plus, old 2015 Biff immediately works the time machine perfectly to go to 1955 and give his young self the almanac. Then, he brings it back! Why? Let Doc and Marty be trapped and try to figure something out. Maybe they could build another time machine in the dystopian 1985 but they would need money and probably new jobs and it would take years. And how did Biff get back to the same 2015 since he altered all future events back in 1955? This sequel script has more holes than a Swiss cheese. Turn off your brain and enjoy this complete mess. I only gave it five stars because I love ripping it apart.
