Searching for an objective opinion

Matthew Sawrey, Thuderbolt writes:

The idea of objective criticism has come up a lot in recent conversations I’ve been having about games. But what is an objective opinion? A Google definition search of objectivity tells me that it is a “judgment [sic] based on observable phenomena and uninfluenced by emotions or personal prejudices.” So is the following statement an objective opinion?

Sailing in The Legend of Zelda: The Wind Waker is dull.

Let’s analyse. The sentence is a judgement. Sailing is an observable phenomena. But the word dull? That sounds somewhat emotive. And thinking that something is dull might be an opinion informed by personal prejudice. Too subjective; maybe it needs some qualifiers. Let’s try again.
