You may disagree as much as you like Royandsyl but do explain what is "not good enough" and why, whether he looks or sound the part (or not, in your opinion) it makes a difference.
The Labour Party are, at this point, going to vote on their leader. You don't say if you are interested in voting Labour but if you are then, in this instance, aren't you looking at the direction of the Labour Party? Obviously, if you are not this election is not so relevant to you. When it comes to the next general election you will be able to decide, after four and a half years, whether you want the policies of one party or another and, if it what decides your vote, whether any of the leader on offer would make a good PM.
