So confusing, it's ridiculous

Rating: 4/10 (31 March 2000)

"Back to the Future" was a wonderful movie. I wouldn't mind taking my kids to it if it weren't for the mild language and the little bits of sexual innuendo.
However, I have to say that "Back to the Future II" /doesn't/ work for me. OK, it's entertaining, to a certain extent. But what killed it for me was its logistical errors. Sure, Dr. Brown (played wonderfully by Christopher Lloyd) and Marty (the star of the movie, Michael J. Fox) go ahead into time to "the amazing year" 2015. And they stop Marty, Jr., Marty's son, from being a part of a crime that was the idea of Griff, Biff's grandson (both played by Thomas J. Wilson). By the way, I would have thought that Biff wouldn't have any grandchildren, let along children in this being that George, Marty's dad, stood up to him. The rest, I'm not even going to go there.
But, then, Biff gets wind of the whole situation with the time machine, not to mention that Marty wants to profit from it by buying a sports almanac for the years 1950-2000. He steals the DeLorean behind Doc and Marty's backs to give the book to young Biff. And it's obvious to me that not only would George McFly get killed by Biff and that Doc Brown would be committed to a mental institution, but also that old Biff would probably get stuck in 1955 because the DeLorean would have disappeared something like everything else that changed with Marty's meddling.
But, I don't know. I guess Zemekis (sp) needed a sequel to "Back to the Future."
