So you've crash landed in the Sahara desert and the only thing on your airplane was Modelo Especial and Matthew McConaughey. Luckily for you that Especial tastes like water. Imagine Corona, then dump that Corona into a vat of water, now you have Especial. No Bueno. So you won't die of thirst, and with Matt along for the ride, who knows, maybe you'll find yourself in the middle of an adventure.
I'll give it a thumbs up for those days when you're burning up, and you need something smooth and watered down. Otherwise, find something with more flavor.
