Open Question: Is Sylvester Stallone a terrible actor and screenwriter?

I'm not a big fan of Sylvester Stallone, I've only seen him in the first Rocky movie which was very good. But Stallone has won 10 Razzie Awards and 19 Razzie nominations for either Worst Actor and/or Worst Screenplay. He even won a Razzie Award for Worst Actor of the Decade in 1990 and Worst Actor of the Century in 2000. Well, for the first Rocky movie, he was very well recieved because he was nominated at the Oscars, Golden Globes and B.A.F.T.A.s for Best Leading Actor and Best Screenplay.
