Whats the argument against the debates at this point? You could say 'This isn't America, we aren't electing a president' but then Theresa May is going up and down the country in a bus emblazoned with 'Theresa May for Britain' that doesn't even mention she's a member of the Conservative Party so that argument's out the window.
1/5th of the country watched the debates the first time round so surely that's a good thing?
