Yesterday (2019)

This film is a high concept film, one where the Beatles and several other things don't exist, except to Jack Malik (Himesh Patel).
Jack is a struggling musician and most of his friends aren't truly supportive except for his tireless manager/BFF, Ellie (the great Lily James) and the epic loser and bumbling idiot Rocky (Joel Fry), though he means well.
But then, for whatever reason, the world's power goes out for a mere 12 seconds and he gets hit by a bus. As he wakes up in the hospital, determined to go back to teaching (a truly normal position), he soon discovers that no one else knows who the Beatles are, in addition to the band Oasis, the drink Coca-Cola and cigarettes. So Jack's music career takes off rapidly. But he knows he's a fraud and Ellie can't or doesn't want to come with him, refusing to leave her teaching position, though she seems to enjoy it. She wants him to become famous for both of them.
Despite Jack becoming an insta-star, with established stars such as Ed Sheeran (himself), giving him credit for being the best, he's deeply unhappy.
Where the film starts to slightly go off its rails is when Jack meets two others (one Russian, one British), who also remember the Beatles though an explanation is never given. They aren't pissed at him for doing what he's doing but glad that the rest of the world can know the Beatles. And they unearth John Lennon's (Robert Carlyle's) address. He wasn't assassinated and Jack goes to meet him. John may not have been successful, but he was happy and that in itself is success.
This inspires Jack to give up his music, releasing the songs for free and getting a mundane job teaching but he has Ellie, which is all that matters to him. He's happy, that's more important than money and fame.
While the film is good, with great performances, I just found parts just odd. Like the lack of explanation on how the two others also remembered the Beatles, where they also knocked unconscious during the power outage? I need to know these things. If John Lennon is still alive, wouldn't he know and recognize that these songs told his story?  How come someone hadn't invited the liquid Coke and cigarettes? It's just odd. How did the writers decide what to keep and what to take away?
Despite these glaring omissions, I still really liked the film, filled with natural performances and some witty lines tossed in. Grade: B
Side Notes:
-Pay attention to some good cameos from Kate McKinnon (as the nasty, greedy manager), Poldark's Elise Chappell, and Lamorne Morris.
-Harry Potter also was never written. Seriously, J.K. Rowling, what happened?
-Though Jack is of Indian descent, his nationality is not a plot point or even mentioned, which is so refreshing to see in itself.
-Jack's father (Sanjeev Bhaskar) is super annoying and never realized Jack's talent and doesn't even recognize Ed Sheeran in his own house.
-Jack's true talent is memorizing all those songs, that is no small feat.
-I'm glad Ellie and Jack didn't have a one-night stand, as that is just so cliche.
-The studio where Jack records for the first time has the greatest name: Tracks on the Tracks.
