I've just finished watching, so here's my thoughts..
I loved the fella who sang the Adele song and the Welsh choir.
I was amazed at the last couple, but she was out of tune twice and (as usual) Simon was right, he would be better on his own.
I nearly pissed myself laughing at that woman when she said "he looks like an owl dun he"
Finally, I'm outraged by the German being booed... why is this acceptable? If he was booed for being gay/pakistani/black/Scottish/Irish/Iraqi/whatever, there would be a public outcry but because he's German, its ok?? Smh.. I hope he wins!
