Parts I and II should be watched Back to Back!

Rating: 10/10 (20 June 2015)

That's because they are mirror versions of the same movie, showing how "the time-warp continuum" effect changes everything, both in the past and the future. (An unproven time travel theory "made fun of" in several movies, including "Milllenium". Also de-bunked in the 2 new "Star Trek" movies as old Spock meets young Spock face-to-face.) A genius of an idea born out of necessity, as "George McFly's" actor failed to "sign-up" for Part II! The DeLorean auto was a great choice as a time machine. Michael J. Fox, Christopher Lloyd, and Lea Thompson carry the entire series. Mary Steenburgen in Part III is wonderful. "Einstein-the Dog" deserves a canine "Oscar" award! Basically a "fish-out-of water" classic, if follows the mis-adventures of two bumbling "nerds" as they stumble through time, in three different movies, from 1885 to 2015 with a constantly malfunctioning time machine, leaving behind messy continuity errors that need to be cleaned up to avoid disastrous events in time. Clever use of special effects (all optical) abound throughout. Much use of split screen as in "Parent Trap". Michael appears as his own "daughter" in drag (part II) and looks wonderful (though more than a bit creepy!) A few almost-innocent racist comments and situations, including two lines edited out (on the DVD version) involving the timeliness of the words "colored and black" in 1955. Easily Fox and Lloyd's best movie roles "of-all-time".
