I think Eminem did pretty good in 8 Mile. Not that he was spectular or anything, but by far the best rapper turned actor performance in a long time.
(BTW, I am not an Eminem or a rap fan by any stretch of the imagination..I actually HATE rap, but I have to give credit where credit is due and I think Eminem did a decent job with his movie)
