This film takes you on a musical journey from the late 50's to the early 70's. It does the time travel well, with appropriate fashions, cars, styles, and musical genres. Some thinly disguised characters (Brian Wilson) are there for the spotting, and all the main characters are well-acted and convincing. What lets it down is the fact that the music and songs do not live up to the period(s) portrayed. It is hard to engage with the featured numbers, they do not stick in your head, and for me, not one tune was memorable. Nonetheless, a solid attempt to portray the turbulent times of the music business, and if you are over 50, you may well enjoy a trip down memory lane.
