Many Flaws with these movies
I don’t know about you, but I have serious issues with these movies. Okay, so Wyld Stallyns music becomes a uniting force in the world creating a utopian society in the future. Bills father was about to send him to military school and in the process he would have broken up the band and Bill and Ted wouldn’t have become who they are destined to be. In an effort to maintain their time line the future sends back Rufus to make sure they pass their history report, thus creating a causality loop or John Connor Paradox. (John Connors birth would have never occurred if a Terminator were not sent back in time to stop his birth) My understanding of temporal mechanics, limited as it may be, forces me to not accept this as possible. The ripples on the water can not precede the pebble, so to speak.
Then in the sequel De Nomolos attempts to go back in time in order to stop Wyld Stallyns from winning the battle of the bands. We then realize that if he hadn’t gone back in time Bill and Ted would have never had a time machine available in order to go back in time to take music lessons and subsequently win the battle of the band creating another John Connor Paradox, and raising several other issues as well.
First of all in the first movie we learn that the clock in San Dimas is always running but they are some how able to leave the battle of the bands for several months in order to learn how to play their instruments, this contradicts their own laws of time travel.
Secondly, since this all needed to occur in order to create the future he came from wouldn’t De Nomolos know that he was doomed to failure. As demonstrated by the Twelve Monkeys Principal a time traveler can see his own imprint on history, recorded in the historical record. The only difference is that there was an immense biological disaster in Twelve Monkeys that explained the lack of a complete historical record, the idyllic future from Bill and Ted would rule out this possibility. One could argue that the government covered up De Nomolos involvement to ensure events transpired uninterrupted, but I don’t feel that this type of Orwellian cover-up could occur in the type of society described in the movie.
Another serious problem with the first film is the fact that they kidnap key members of history without any thought to the repercussions. I know that if someone just stepped out of a phone booth that appeared out no where, kidnapped me, and took me hundreds or even thousands of years into the future my world view would be irrevocably altered. Not only were these individuals exposed to technologies far beyond their own understanding, but they were present at an A+ level history report detailing their entire existence including things that had yet to occur in their lives including, one can only assume, the date of their death (A historical speech about Abe Lincoln is pretty tough to do without including a little incident a Ford’s Theater). I can only imagine what some of these people would do with that information.
