Answer:
The correct answer is Let's just face it. People who hate reality shows are really just old, humorless sourpusses.
Explanation:
The second sentence is a judgement towards reality shows, but it is based on an argument and uses the name of the subject as an argument for the judgement. This means that the judgement is not baseless.
The third sentence contains a judgement about people wanting to be on TV shows, but the judgement is based on an argument; numerical statistics of TV ratings. This means that the judgement is not baseless.
The fourth sentence is a sound opinion on a matter that has a full argument with evidences.
The only sentence that contains no arguments whatsoever about the opinion is the first sentence. It is a judgement towards people who like watching reality shows without giving any evidence about the way they are labelled. It is not a proper judgement; it is intended as an insult.
