How to Write an Epic Trailer Soundtrack

A bit tacky and a bit cliché, but it seems to me that it achieves the goal the writer set for himself. The explanations also seem very general to me, even for beginners, but if that is his goal... What do you think?

Then I will listen to it and express my opinion; for the moment, I say that a few years ago I stumbled upon another tutorial by this girl by chance, and what I liked most was her voice (while she speaks).

I should preface, however, that my idea of "epic" is a bit different, because I am a bit tired of the usual cinema pieces (especially trailers) where the choir performs the usual imperious part along with the strings, some of which perform the usual glissando in the high register, and the horns (I repeat the term specifically to convey the sense of nausea) perform a super powerful but very predictable part; what agony.

No nonsense: Harmony, Counterpoint and Fugue.

Here is some "epic music" written with all the bells and whistles:
