What does disliking liking something and commenting on it a bad concept?

Rating: Null/10 (2 March 2008)

Someone recently said, "I don't think anybody that has seen Will's movies and disliked them should be commenting on here." That is nonsense. Apparently, this person has a love of Will Ferrell's movies. This fact makes the person who said the above statement biased. Ferrell's films are all the same --- even using many of the same casts --- and Ferrell plays the same character continuously. This concept soon becomes evident as with previous goof-balls such as Jim Carrey. . . I neither hate nor love Ferrell's film, but I do know when I am watching a quality film.
Just because you like something, does not make it good! No offense to all the people who will dislike this statement. On the other hand, the dislike of something does not mean it is not a bit information with quality. if had to grade this film as A, B, C, D or F, "Semi-pro" would be a "C."
