No doubt they will be crap. Sorry, biopics always are!   Fine it you don't know their stories inside and out, but almost every detail of the four main Beatles' lives has been picked over to the bone marrow. The contradiction of Lennon and Harrison's personalities, drugs alcohol and flings, are difficult to reflect, (the domestic bliss myth of Lennon's 70's years etc). At least three Beatles have some unsavoury aspects in periods of their lives, that are often glossed over. What is truth, and whose truth? Some films capture atmosphere, but not truth, as they usually get some of the casting wrong, the music wrong, and the historical facts wrong, (always 'dramatic license'). Also, often the 'truth' is doctored in biopics to get a lower age rating audience certification. This is just yet more merchandising and promotion of the Beatles to flog the horse in as many commercial ways as they can while copyright exists on their recordings.
