So in this movie old Biff goes back in time to give the sports almanac to young Biff. Doc and Marty go back to 1955 to stop him and go through all kinds of trouble. Wouldnt it have been easier to go back to 2015 and fish the almanac out of the trash? It always kind of bugged me.
And wouldnt the whole town be kind of pissed at Doc Brown for breaking the clock tower? I mean the cop saw him getting set up and Doc applied for a permit to run his experiment.
