And the Mythology Lovers would continue to get unnecessarily angry because a TV show failed to meet their expectations.
It's fine that you were satisfied with the ending and explanations (or lack thereof) for the mythology elements that were introduced, but it's kind of obnoxious to say that people are wrong to have expected some of the larger questions to have been addressed beyond vague mysticism at best and nothing at worst.
I think if you introduce giant Egyptian fertility statues, temples, stone butt plugs blocking all the evil of the world, and so forth, you should address who built the stuff. Especially when you had entire episodes of people jumping back and forth through time. Otherwise it just looks like you're introducing it for the cool factor instead of having it be meaningful to the plot.
I say this as someone who has loved the show from the start and who is not angry about it in the slightest, so please don't dismiss people so lightly because their complaint doesn't match with your impression of the series or finale.
