Lisa is a major unknown quantity insofar as there is a lot of talk of her being a one trick pony, and all being tired of same-old, same-old...
Until we have seen
a) if she is any good at ballroom/other styles,
b) if she works hard and improves (Louis, Denise etc are limited in their ability to produce a 'journey' story in the remaining time as all are at a high standard already)
c) if we get training VTs and not comedy ones - we know she can act, but Lisa is a great example of being one who could majorly benefit from training VTs to show her personality as opposed to "i'm mad me" approach which has so far come across due to the sketches (?) and the dances they've done
I'm not a massive Lisa fan btw, but she's an example ... I definitely think there will be a surprise in the final 2 (i.e. only one of Louis, Denise, Dani, Kimberley)
