This film is a work of art in every way--the singers are incredibly talented, the acting is full of emotion, and the director just went completely out of the box with this one. I do warn, though, that there is some material that may not be age-appropriate for younger audiences. There's a good amount of blatant or implied drug use---pantomiming smoking pot, drinking fruit punch laced with LSD, smoking cigarettes, war veterans becoming addicted to morphine, and many scenes with alcohol consumption--one where the characters end up passing out drunk. There's also a small bit of nudity: a couple is shown waking up in bed together with sheets covering most of their bodies, and a couple minutes of a set of underwater scenes where various nude characters are artfully placed so there is no explicit content actually shown (although you do see the side view of a woman's breasts and various rear-ends), and its purpose seems more to display the main characters' deep love for one another. The violence might be iffy for some children. There's some mild violence with maybe a punch or two, but there's also some violence where people are being physically beaten into compliance with considerable blood, war scenes showing men being shot and killed (although with almost no blood), and even one child (though his death is not shown...only the body at his funeral). The "Strawberry Fields Forever" number also uses strawberries and their juice to symbolize the bloody war going on, and some kids may find the visuals disturbing. Lastly, there are some parts of this movie that are just plain weird and may frighten younger audiences---specifically, the war protest rally at the end of the "Dear Prudence" number, where some protesters are in creepy-looking costumes, which soon after is followed by the circus number "Being for the Benefit of Mr. Kite," which includes some strange, possibly grotesque-looking creatures (circus performers in costume), which personally scared the crap out of me the first time I saw it.....I still have to kind of look away because they just look creepy.
On the positive side, it does send a good (although at times, difficult to detect) message that says to stand up for what you believe in and do what you know is right---even if it means going against the mainstream grain and authority.
But no matter, I think this is a wonderful movie with real emotion that portrays part of the not-so-pretty side of the '60s and '70s using the music that defined the era. Absolutely recommended for mature kids and teens.
