Because your expectations, film knowledge, HT Setup & environment as well as personal senses such as sight, hearing and sensitivity/tolerance to those senses are probably different than Tony's so I can understand why you would think it's fine while he thinks it terrible.
How well do you know this film? As your bolded comment appears to suggest to me that you're not aware of certain aspects of how this movie was filmed. Also, it would help if you note which scenes you're talking about?
