Well if that's your view, the money is already wasted so why not at least enjoy what you're seeing or does being negative make you feel better about "all the waste"? It rather seems like you're cutting off your nose to spite your face...
Would GB failing miserably, transport chaos and the legacy/payback being negated be a good thing? Would it make you feel happier? If so, why? Surely we have to make the most of this given that the die is cast??
Anyway, if you're that worried about what it's cost you personally maybe the rest of us could have a whip round to make you feel better...
