Bella is awful. She can't sustain her voice or hold a note to save her life. Sometimes it sounds pretty, but that's usually in the very first few seconds. Beyond that, you can see her head shaking as her voice quivers, while she struggles to control her extremely limited range. And it's not that special either. There are plenty of her types around, with better skills.
Samantha is FANTASTIC! I loved "Scream" from last week more so:

She is an incredible performer AND manages to sing well while executing the routines. Such a sweetheart, too. I hope she makes the Top 5.
Send Shiane home. She needs to mature more.
Nathaniel and The Collective are great, too. Nathaniel's "Red" was amazing this week. Jason is so-so.
