Calling Dark Lord overrated has nothing to do with its rarity. It has to do with its hype in relation to the quality of the product. It might be a good beer for some, but I found it to be less than impressive, and I'm not the only person who thinks so. I don't put down beer because it is popular or because everyone loves it. I called it overrated because that's what I think of it. Selling tickets to get in line for a bottle of beer you then have to pay for makes this one of the most hyped releases in the country. It is nowhere near as good as the hype or most of the reviews. That's pretty much what overrated means, isn't it?
Also, this is a thread about Three Floyds. It is pretty much pertinent to the conversation. Randomly calling out Westy 12 in a quad conversation is not a very good comparison to talking about a beer from a brewery in a thread about that brewery. I'm not being a dick here, I just have a varying opinion, and if nobody had one of those, we'd all be carbon copies and boring.
Sorry it doesn't follow your line of thought, but my opinion, and those who disagree with you are just as valid to share what they think. You say "amazing", I say "middling at best". Opinions. Rad.
