Answer:
Hasty generalization
Explanation:
This is an example of a hasty generalization. A hasty generalization is a type of fallacy in which a conclusion is not logically justified because of lack of evidence or because the evidence is biased. In this case, the speaker is making this error by claiming that all French movies are dull when he has only seen three. This is a very small sample and, therefore, the conclusion is not logically justified.
