I know people won't like this post, but I have been an Alizee fan for a LONG time and this is what I am seeing...
I feel the same way Lucas does. Alizee's been using playback so long now and so many times, it's getting strange. I feel the dancing gives her a reason to use playback, like an excuse. I went to the 5 concerts in Mexico and I saw Alizee sing live. She has it in her, but I dont think she wants to do that much anymore.
I mean Alizee is a singer. I don't know too many singers that don't love to sing live. If you told them to do playback, they would be upset. But in the case with Alizee, It think it's her choice to do playback so she never has to sing live.
As for Alizee being in movies, she's going to need to work on her English and lose the Tattoos or she's just going to have to stick to doing French movies.
Melissa Mars was at the same RFM Summer Live as Alizee. She sang live. Also she's fly's to the USA and shoots movies. As for Alizee being too old to be in movies (30 years old), Melissa is 32 years old and a woman and shooting movies in Hollywood. Could Alizee does that too?? No...because I dont think she wants to put forth the effort. I'm not saying that is a bad thing, I just think Alizee wants to raise her daughter and sit on the beach and eat out with Dancer Man. Nothing wrong with that, but I don't see the fire in her eyes to make her career better. If we did not have Sony pushing her or danse avec les stars asking her to be on it, I don't think we would be hearing for Alizee right now.
If you have not seen it, take a look at all the upcoming movies Melissa will be in theaters soon in the USA.
