Gilgamesh: The first and worst text ever written

I have a few questions about Gilgamesh. First, what was Huwawa doing so horribly? They said he was a demon, but they didn't say why... as long as you stayed away from him, my guess is that he wouldn't bother you. This reminded me of the movie Battleship, when the aliens first revealed their ships, they were peaceful up until when the navy attacked them. Maybe they were there for a good cause, but they were not given a chance. And since it said he was the guardian of the forest, the forest may be vulnerable now.
     Second, is that all they're going to do? Are they ever going to go on another journey? Was that the big climax of the book? Because that was not exciting, at all. I'm just going to think that because this was the first text ever written, but they could have done a better job, plot, and detail-wise. This book is genuinely the most boring one I've ever read. The supposedly exciting, action packed parts did not have me off my seat. The fighting scenes, (and all of the scenes in general) lasted like, one sentence and didn't explain or describe squat.
     Also, is Enkidu jealous of Gilgamesh? It seems like it. Gilgamesh seems so proud, full, and sure of himself, while Enkidu is solely worshiping and complimenting Gilgamesh. What's backwards about that, is that Enkidu seems to be doing all of the work and yet he is receiving zero credit for any of his work, while Gilgamesh basks in the glory that is not rightfully his.
      I am skeptical about this book as it doesn't explain things thoroughly, and I am a very visual person so it's rather hard to make out what is happening.

Friend or foe?
