By all means, you should watch "A Star is Born". It is a great movie in which Lady Gaga plays a starring role. It's a remake from a 1976 movie with the same name that starred Barnara Streisand. The 1976 movie became a classic in the eyes of many. You should also listen to the soundtrack separately so you can envision things with your own heart and imagination. That is what this movie is all about...getting in touch with your feelings.
It would be a shame for anyone not to see the movie, regardless of if you saw the 1976 version of it or not. It has an awesome story line and Lady Gaga was fabulous in it as were the others who played in it. So, YES, YES, YES...you certainly should!
