How to tell if a wine is 'good'

You hear about all these wine ratings by critics who may, and probably do, have a completely different palate then your own. Let your own tastebuds be the judge of what wine is 'good'. I personally can't STAND South African Pinotage, I think it tastes like mud, I don't care if it was rated at 94-points. Just because I don't like it doesn't mean other people can't.
There are other factors in determining what makes a wine 'good' such as, whether or not it has any faults(TCA, its a bacteria that makes the wine and cork smell mouldy, like wet cardboard), or if it is well balanced(containing just the right amount of alcohol, fruit, body, tannin, sweetness, and acidity), and complex. The simple answer is just, trust your tastebudes, if you drink it and you don't like it, don't buy it again. If you like it, and nobody else does, drink it anyway.
So you see, go with what you like, and everyone will be happy. Always trust your 'gut'.

All this wine talk is making me thirsty.
