Harry Potter (film series) of 12 Academy Awards. Some critics, fans, and general audiences have expressed disappointment that the "Harry Potter" series did not win any Oscars for its achievements. However, others have pointed out that certain films in the series had uneven reviews, in contrast to the three films of "The Lord of the Rings", for example, which were all critically acclaimed. This has been partially attributed to the "Harry Potter" franchise going through several directors with their own styles in contrast to the "Lord of the Rings" trilogy, which was filmed in one massive undertaking by the same director, writer, and producer.
