Does a movie critic need to make their own movie in order to comment on a movie?
Do food critics need to offer up their own food in order to be accepted?
And so on.
The world is full of people offering up opinions on whatever without providing their own for comment on just about every topic imaginable. Get over it.
Oh, I didn't realize you were offering an unsolicited critique to jrista's photos, in which case it is nothing short of a personal attack because his photos are not "junk" (not to me at least). Maybe you need an eye exam.
Commenting on photo on CR to movie / food critics ... clutching straws are we? Movie / food critics exist as a source of information (whether biased or unbiased) for prospective customers of a particular product. I don't understand, was jrista selling something which you were critiquing and coming up with the "junk" opinion?
As far as your comments regarding movie critics, the only thing that comes to mind after reading your post is ... Rotten Tomatoes ... hell, it could even be Pure Mashed Potatoes!
