the premise for the "Yesterday" movie is interesting...but it really is a fantasy movie on so many levels...the most obvious one being that som many other acts would never have existed if not for The Beatles, and so many other facets and trends of everyday life would not even exist if not for their influence.

In other words, in a world where The Beatles domino is removed, all the other dominoes after that never have the chance to fall in exactly the same way.
