His response to the election being called was typically muted. Just so bleh and unenthusiastic. Yes he managed to say we want a fairer society etc. and I agree with him, but he said it in a totally unengaging, boring way with a look on his face like "oh harrumph I suppose I'd better cobble together something to say", as if he was really more concerned with getting the coffees in.
A leader of the opposition should be really going for it in that situation, saying let's do this, this is our chance to get rid of this money-snatching Tory government that's bent on destroying disability protection, workers' rights, the NHS and the education system. Saying something stirring and passionate about the NHS, education and other public services that are dying before our eyes and affecting so many people.
Then on PM there was a labour guy being unbelievably awkward and crap when asked if Corbyn could win it - his answer was all over the place, not wanting to say JC could win unless he looked ridiculous, not wanting to say he couldn't. They need to be trying to give the country a strong, vocal alternative and instead they're just cringing and looking sheepish.
Rhetoric, charisma and personal appeal do matter. You can be good at them and still be genuine - it's about being able to engage with people, communicate ideas and come across like you have passion, belief, a sense of justice, a sense of humour. Barack Obama is an example of someone who's good at it - it doesn't mean he's all surface or not genuine.
JC not only doesn't have these skills, he also comes over like he just can't be arsed and is mildly irritated at having to make a statement at all.
