I'm glad Pixie's gone and I don't care if that makes me sound like a bitch. 
She was so obviously trained, she was consistently not picked up on things like not closing her feet that others are criticised for, Trent just put in high/long leg things every dance to impress people, and she had no personality as far as I could tell. She was very ungracious squealing with joy after Craig saved her.
I'm glad Simon went through and I didn't mind him collapsing to the floor; I felt it was genuine shock, and that he can't really believe he's still there, whereas Pixie seemed to just assume she was going to stay in. Trent's face was like thunder when they got called for the dance-off, too.
Caroline's AT had too much trickery and not enough of an intimate feel. Jake was terrific and what a clever, sparkling routine Janette gave him. Have completely forgotten Mark's dance. Frankie's didn't have enough salsa, it was a rubbish song and it just looked trashy and slutty, and not in a good way.
digerd, I think someone on here said Jake went to stage school. I don't know the details of how much he's danced though.
