Straight Outta Compton 9/10.
Formulaic, but IMMENSELY ENJOYABLE. Solid performances, distinctive 90s film making and an incredible soundtrack propelling the film. The movie felt as 'old school' as the time period it portrays. Maybe the film will be less impacting for those not present for the Hip-Hop of the late 80s and early 90s. I admit a bit of [personal bias here for the source material, but the film is well made and very fun to watch regardless.
There is a part in the film where they play the noisy opening bars of N.W.A's titular album, "Straight Outta Compton", and it is as electrifying and vital sounding as 27 years ago. When the bars of "Fuck Tha Police" the parallel would be comical to modern and recent events in the US if it were not so intensely raw and earnest in composition.
Highly enjoyable.
