You did not mock the film. You mocked his liking.
Which is because of the quality of the film and not his tastes in general. Regardless of how he would have responded I would have called the film terrible and scoffed at the thought that AOTC could possibly be on par with Rogue One.
Also if this is a personal insult then you have insulted me dozens of times for liking TFA so practice what you preach.
