I think Straight Outta Compton is one of the greatest biopics, but I am biased on that one, obviously. There are some things the Academy gets wrong and it's important to call them on it. But in other instances, there are simply just better actors. They're doing a better job than they've done, but there's still room for improvement.
Bun BI knew that Sylvester Stallone's involvement would outweigh everything else from the film. I think people went into Creed expecting a boxing movie and something that superficially ties Stallone in, but Creed was really well written.
