I enjoyed the 3rd movie, the western. I did not know at the time that a Clint Eastwood movie had done the same thing that Marty McFly did with wearing the bullet proof poncho. That makes a lot more sense why McFly was calling himself Clint Eastwood, so they were openly acknowledging they were ripping off an idea from a Clint Eastwood movie, and also explains where Marty got the idea from. Good thing in both movies that nobody shot at their face.
I enjoyed the part of the 2nd movie that tried to predict what future tech would be like. Funny how can they could get it both so right and so wrong all at the same time. Got pretty close predicting the Cubs would win the 2015 world series. Just off by 1 year.
Unfortunately the plot of the 2nd movie was pure garbage, and once they left the future, it was a complete mess.
