Negative Positive
Title: sequels flawed...
Review: BTTF2: Biff goes to 1955, hands sports almanac to himself and comes back to 2015. Hill Valley should've been changed to a gloomy ghetto when he arrived back to 2015. but in the movie, nothing changed. (sorry to put a splinter in such a fine movie)plus.. if Marty and Jennifer travel to future together, how could they meet their old selves? Whatever the future written should've been erased as soon as they arrive to the future. starting with their kids.BTTF3: Delorean needs fuel? why? It's been already modified to run on left over food trash by end of the original movie.(MR.Fusion). plus Doc had 2 Deloreans to work with in 1885 (One sitting in the cave and one marty brought in)...
