Great idea apparently hijacked and left the biggest question unanswered.

Rating: 3/10 (15 September 2019)

I'm not a big Beatles fan, but I'm a musician and have a lot of respect for their legacy. I'm also not under 35, as one person suggested of anyone who doesn't rate this movie highly.
The story was interesting, and at first I was enjoying this movie. Kate McKinnon is great, and she really carries the whole cast. But it was irritating me at it went on.
Throughout the movie, I was waiting for the explanation. How did this happen? There were TWO other people who knew of the Beatles. How? Where did the Beatles go? What is the connection with these other two people?
I'm sorry... I guess a lot of people are ok with watching a movie where the entire universe gets altered with no explanation or reason for it.
Hey... the world just ended! HOW? Who cares... let's just tell a cheesy love story built around the implication that the Beatles' music would have as big, or an even bigger impact now than it did in the late 60's. Well, it's a much different world now and there have been many great songwriters other than the Beatles.
Regardless, the biggest problem with this movie is the incomplete story line. How TF did this situation occur? It's written in the trivia that the original writer was including more of the alternate universe in the story, where the secondary one decided to ignore that and focus on the incredibly awkward love story. Bad decision.
Marty McFly traveled to alternate pasts and futures... but we know how and why. There were multiple love stories intertwined in those movies, but it never left major ends untied... except for the purpose of sequels, but I won't expect to see one for this movie.
Malcolm McDowell chased David Warner as Jack the Ripper into the future. The love story was structured around the method of their time travel. We knew how it worked and why.
Ironically, the female love interest involves the same actress in both of my examples, but they were great movies that didn't leave me wondering WTF happened at the end.
I'll look forward to someone taking this idea and doing it right.... someday. Perhaps with the music of Led Zeppelin.
