Quality film.
I thoroughly enjoyed 'Straight Outta Compton', it had me gripped all the way through. That's despite me having little to no knowledge of N.W.A, I knew of their name and of Ice Cube and Dr. Dre but basically zilch about their actual story. I couldn't comment on how true it is to history, but as a film it's fantastic.
You have great performances from O'Shea Jackson Jr., Corey Hawkins, Jason Mitchell and Paul Giamatti. Mitchell impressed me most as Eazy-E, while the casting of Jackson as Ice Cube - his father, of course - was a masterstroke. All the cast do very well, in truth.
I love how gritty the film is too, it feels real - at least as real as film can get. There is some neat cinematography in there, while the music is entwinned nicely. The pacing is almost perfect, aside from a few moments in the middle. I also rate how it all ends, in terms of the story but also with the end credits. There's heart in there.
