Maybe it works for people who like having everything filtered through a modern cinematic cgi filter. In this case, sure, it is a neat tool for seeing how a hollywood studio might have imagined events of the past to look like. At least you admit upfront here that they are "fantastical imaginations" of historical events, but maybe you should clarify that on the website too.
I've always found it better to hear from actual historians, or better yet, dive into the source material when learning about events of the past. This takes some actual work and requires doing good research. It would be nice if AI could help those folks do their jobs more easily instead of being used to generate more fake looking slop.
