Boy, am I excited xD
It will be interesting to see what they do with it for sure. Change the story around a bit and make it a bit darker (just like "The Jungle Book")? Sounds great. And as what Borborigmus pointed out, since the original Lion King was based on Shakespeare's "Hamlet", it will give them lots of wiggle room for darker/scarier stuff. And just imagining all of the characters as real life animals seems pretty cool too
I predict this will either be just ok or great; I think it will be really difficult for them to make this bad. But yeah, I know the CGI will be pawesome!!
