I used to think the same way when I was 10 years old. But now I rather watch a good movie; genre is irrelevant. I think your argument is bad movies vs good movies, and not genre vs genre. I understand people have preferences, but it only clouds judgment.
I think his point was that a genre like comedy, when done right, can transcend low production values, bad acting, and cheap sets. It would be harder to convince the audience to take something seriously (which is necessary for a drama) when the sound is crappy, the camera quality is dirty and the back drops are dull and static. None of things matter if a comedy is written correctly.
Stand-up comics make people laugh for hours with nothing but an empty stage and a microphone. Could you go up on a stage in front of 10,000 people with nothing but a microphone and engage them in a dramatic tale for over an hour? I know the mediums are different but both are essentially story tellers.
