Back to the Past

Back to the Future Part II was somehow wiped from my memory ('cept for a few bits) so now it's back in my mind.

Never saw Back to the Future Part III so now I have that one in my brain. I'm surprised w/the repetitive plot devices in both of these that they just didn't keep making more of these films and traverse to other historic periods or farther into the future. Wouldn't be surprised if this story gets revisited w/modern film technology at some point in our future. Then we can all go back to the future in our future. Yay!
