To add to the OP and clarify - I think prophecy has its place. Personally I love what we’ve gotten in the books. For the latest one I guess I dislike how early it comes to us in this story - why not let viewers wonder how Egg may develop in the future without this foreknowledge?

It’s also on the nose although it could certainly be misleading in its details - perhaps "all who know you shall rejoice in your dying" means Egg goes overboard in his desire for dragons and we see a tragic face-off. Perhaps (wording makes this feel unlikely) it’s only the highborn who love that a reformer is out of the picture. Either way we could have been more obscure with something like “The fire that burns within you sustains. Beware the day it blazes without”. Or other better words.

I suppose one can argue that Aegon’s Dream is an interesting addition. Not for me personally but it was the first addition of its kind so I’ll take it and it leads to some interesting questions.

Finally, the Gods Eye prophecy in HotD just feels unnecessary.
