[EX Q]: At first listen, I was not at all impressed. Although it's a catchy beat, the lyrics are cliche and some of them pretty inappropriate. But then another album comes along and my opinion changes. And that's what this is. Not nearly as impressive in production quality but still better than most music out there, and that's why it earns its keeps. Good job, Linkin Park!Update:Now that I've had more listens though, I'm impressed with it.
[EX A]: Bad review

[EX Q]: I purchased this little converter for my Samsung 3D TV. It works great. The best part is that unlike other converters in it's price range - I can now receive all of the TV channels without having to hook up an extra antenna which was costing me $80/month before.
[EX A]: Good Review

[EX Q]: A typical John Sanford book.
