I don't know your age, so it may have just been different for your time, but when I was a kid the pyramids were mysterious and people literally thought they may be magical. No one knew what lay beyond the sealed doors and it could have been anything. Plus, how in the world did they ever even build them? Maybe aliens helped?
Turns out it was just a great way to stack rocks and even their primitive technology was more than sufficient to move blocks. The treasures inside were, indeed, fascinating ... but they also could have turned out to be Al Capone's Vault.
That's my worry, that something magical in our imaginations will just end up as crass CGI. Jackson's LoTR could have ended up the same way, as well, and he did a decent job of it so here's hoping this crew can at least match that. The animated LoTR is still my favorite and likely always will be.But maybe it sounds better in the way it's presented written in the Silmarilion etc. and is only going to end up pure CGI schlock on screen.
I know these shows are supposed to be fantastic, but they just don't seem like my kind of thing. Real world drama just doesn't do it for me.
