Looking back at the UK election debate

I could watch the latest UK election debate live in Israel on Sky News and was fascinated to see these professional debaters in action. In the House of Commons, the UK parliament, debates are very lively and real. In this televised election debate I was a bit disappointed; candidates were hardly listening to one another and tried to find anchor to revert back to their scripts to make a key point.

Where does it get interesting and convincing? When the debaters go off-script and truly try to convince their audience from the heart. They should have the courage to debate like they do in parliament, and stop trying to nail that sound bite. Dry statistics do not move crowds.
The other interesting thing I noticed is the power of the face expression when an opponent makes a point caught by the ever-present cameras. Face expressions reveal one someone thinks an opponent made a really good point.
