I think my only regret is not watching this movie in the cinema, on a big screen, to get the full experience. It's wonderful! The opening scene, the music, the script, the characters evoke a myriad of emotions.
There is, however, no way of mentioning Dreamgirls without giving a mental standing ovation to Jennifer Hudson. She simply stole the show, which is actually a compliment to the other stars, especially Beyonce, that they allowed a 'newbie' to take such role while they played off her. With the famous 'I'm telling you I'm not going', she sealed the deal for her oscar.
The DVD is a collector's item, the movie is all that, and then some!
