"Back to the Future" Trilogy

Recently I have watched the "Back to the Future" Trilogy. These movies really support the idea of time travel. Since there is so much information in the three movies, I am just going to try to do a short summary of all three and how they are relating to travelling through time. First, in the title, it is kind of obvious. The movies surround the life of a boy whose name is Marty and a man who everyone calls 'The Doc'. The Doc is a mad scientist who creates lots of different machines. One day, he decides to create a, you guessed it, time machine. This time machine is a little different than others. It needs a little bit more to get it going. Plutonium. The movies have many similarities, but also differences. They are similar by the fact that they all involve time travel, obviously. They also involve going into the future or the past, changing one little thing, which then changes some other part in time. This kind of got confusing, but you get the hang of things. There differences are that each movie travels to a different part of time for different reasons. In the first movie, The Doc first shows Marty the time machine and how it works. The Doc ends up getting shot by tourists and Marty uses the time machine to go back in time really just to check it out. For some background info, Marty's father met his mom when Marty's mom's dad (Marty's grandfather)  runs over Marty's father with a car. They fall in love and have Marty. Long story short, Marty saves his dad, and causes his mom to fall in love with him instead of meeting Marty's dad. Marty spends most of the movie trying to get his mom and dad together and becoming friends with his dad. He then heads back to the future to find that The Doc had been faking death. In the second movie, The Doc, Marty, and his girlfriend head to the future because apparently, Marty and his girlfriend’s kids are badly behaved and that needs to be fixed. When they get there they find the children. I thought it was really cool because the future at the time the movie was made was 2015 so it suggested that in a couple years we would have flying cars, phone goggles, and voice activated greenhouse overhangs. In the future, there was a book that had all of the winning teams of sports in it. A man finds this and the time machine, goes back in time, and uses the book to become rich. Marty travels back to the past, and finds out that the neighborhoods have gone bad and that the world was just terrible and poor. He also finds that his mother is remarried to the man, whose name is Biff. Marty then travels back to when the man receives the book and spends the movie trying to retrieve it and save the world's past. At the end of the movie, Marty gets a letter from a man that was written by Doc saying that he has been taken back to the old west where the time machine has been buried in the ground. The letter says not to come and find Doc, but Marty does not listen, and finds the buried time machine and travels back to the old west. During this movie, they spend the time trying to get the time machine working, because it also requires gas, which had not been invented yet. Marty gets back to the future, but Doc does not, in trying to save the girl he has fallen in love with. The third movie ends with the Doc coming to Marty's present time, in a 'time train' he has created to the future to find Marty. He has along with him, two children and the women. He goes on to say that he has travelled to their pasts and futures, and has many more stops to go.
