True! It would be interesting to contrast the number of flat earth movies vs. round earth movies. There is no easy way to do that. If I type in "flat earth" on YouTube, the first 50 results contain only one defence of flat earth, the rest is debunking. This might be because 1 in every 50 people believes in flat earth. It might be because for every crackpot clip there are about 50 clips debunking it. It also may be the case that debunking flat earth is popular nowadays. It may even be because YouTube already tweaked their ranking algorithm. However, when I search for "hollow earth", I get almost no debunking clips in the first 50 results. That makes me think that the first two hypotheses I came up with probably don't hold water.
