I think the filmmakers did a terrific job. Obviously, this film is from the Dre/Cube point of view, and we'll never know the full truth of what happened, but their take on it was pretty darn engaging. The rise of West Coast gangsta rap, the money issues, the lifestyle and how it affected these young men, were all well done.
Warner Bros. famously passed on this $29M film, due its budget, which seems so ridiculous. Straight Outta Compton plays like a much larger film. The one part that seems too small is the LA riots. I wish it would have been a $50-$60M film, so that the filmmakers could have added some grandness to it.
I guess my biggest complaint is the near absence of DJ Yella and MC Ren. They have much too little face-time and have barely any dialogue. We don't get a feel for their story whatsoever.
I also think the filmmakers held back a little. This was probably due to studio concerns. There is a terrific hotel room party scene. But I think this movie could have been more hardcore. It is N.W.A. after all.
I really did enjoy it though. The acting was solid. The story moved. They chose the right end point. I feel that the filmmakers did this LA story right, and for that I'm glad.
