I like time travel, provided it makes some lick of sense (and incorporates parallel universes into it's method of operation).
Er... Back to the Future Pt 2?
BTTF2 doesn't utilize parallel timelines, Doc's "1985A" explanation notwithstanding, as all the other stuff involving paradoxes, changing timelines, etc. makes that impossible.
Isn't that a bit like saying "BTTF2 doesn't involve time travel, all of the time travel notwithstanding"
Oy ... I'll try to make my case in a far more clearer and straightforward manner.
In the first film, Marty alters the way his parents met. This initially started to cause Marty and his siblings to fade from existence - as evidenced in the Marty's changing photo of himself and his siblings (along with himself starting to fade away near the end of the film)- before he corrected the course and preserved his and his siblings' future existence. By all indications, this shows that the BTTF Universe consists of only a single, malleable timeline that can be altered by time travelling effects.
In the second film, while preparing to journey back to 1955 from 1985A to undo the tampering 2015 Biff made to the timestream, Doc Brown says that it's okay to leave Jennifer and Einstein in that ugly present, as the world around them will simple reconfigure itself into a more familiar world once they've fixed the past. More evidence that the BTTF Universe consists of a single, malleable timeline.
In the third film, we get more examples of a malleable timeline, as evidenced in the photo of Doc Brown's gravestone that keeps changing everytime he and Marty influence the world of 1885. Again, a single, malleable timeline.
Now, if time travel really did create parallel universes everytime someone travelled back in time to alter history, then there would be no changing photographs, no fading Marty, Jennifer and Einstein would be forever stuck in 1985A, etc. and all the various timelines featured throughout the trilogy would co-exist parallel to one another, completely unaffected by the time travelling events occuring within the films.
