Dance wise, Daniel going now isn't too early, imo anyway.
Very nice bloke with a clearly nice and respecful partnership between him and Kristina, but dance wise not exactly much to write about (for me anyway, i appreciate others might have loved watching him dance). Of the dances he did, I don't think it was enough for him to stay much longer. Probably Jeremy and Carol could have argubly been up there as potential exiting celebs, but, it's not shock dancing wise that he didn't connect.
As a singer, if he is/was as popular as is made out (I have no idea of who he is when his name was announced) then I am sort of surpised his fans didn't keep him in, but as we've see with Nicky from Westlife and Simon from Blue (who ended up in the BT quite a bit), big music fanbases don't always save you alone, you need a larger strictly support overall.
