All the judges even if the difficulty level is low for Lauren they go out and say wow extremely over the top comments for routines where they were all in white (afterlife dance) and also the one where they were in orange and red, routines had very little difficulty but only the emotion alone scored them high scores whilst others can put the same emotion but score low marks, the others have to do both emotion as well as high difficulty level to score the high scores, whilst Lauren I've seen two routines where the difficulty level was low but only emotion (expressions) alone scored them highly.
Saying the above of all the routines for Independence day I liked Lauren and Punit's the best, so they deserved the 30 marks.
Out of the 3 judges, I think Madhuri is the most fair judge. most partial is definitely Remo. He doesn't notice the mistakes the kids make sometimes and only looks at the amount of energy and difficulty level of their routines, last weeks kids routine though it had high difficulty had two errors but he didn't mention it as he is the technical judge he should have noticed the errors.
Remo for everyone else other than Lauren and the kids all others routines if he sees the routine had a lot of difficulty he scores them highly. The other two judges follow his lead when he gives high scores, I've only seen once when the other two scored a 10 and he scored a 9 for a routine.
