I have to say, I dunno if Amber has improved or my attitude has changed but this is like the first time that I truly enjoy her as part of the group... The dynamic is so much better, she looks like she's enjoying herself, etc. Before it was sort of like 4 pretty chicks + Amber, and it didn't help when she disappeared for a good while from performances. Now it looks more like a unified group than before. IN MY OPINION!! But I didn't really pay much attention to Hot Summer, or whatever their previous release was, so maybe this improvement already happened before and I just didn't notice. But I like that she's having 'normal lines' instead of just rapping, especially when I don't find her rapping skills (or the raps in f(x) songs) particularly awesome.
