I thought Danielle's first two performances were very dynamic, and she is full of energy and always in character in the group numbers. She, Steph and Stephanie are the ones I usually notice most in the group numbers (and Jessica, but usually not in a good way). I will admit that Danielle's show 7 performance was lacking the dynamics of the first two. It was a weird routine, the arrangement wasn't right for her voice (the arrangement Keith sang on ADWD would have worked better, I think), and the dance routine was just a mess. Danielle tried her best, but I really don't think any of the other girls could have done anything great with it either. We'll have to see what she does next week to see for sure if that was just an off-week, but I think it was. I would really like to see her get a truly happy song sometime, though.
As for Jenny, she tries hard, but she just bores me. I can't really explain why, and she often looks out-of-place in the group numbers. Also, IMO she has one of the most annoying voices of all the girls (after Emilie and Jessica). And as to Jessica, stage presence is one thing. She does have that, but I don't think she has anything else that is West End level yet. Her voice is weak, her acting is over-the-top, and her dancing is clumsy. I like Jessica as a person and I do think she has potential, but I just don't think she's there yet.
