Honestly, I don't really expect anyone to share my reasons for disliking it. They're my reasons. At the same time... there were things I liked. Just.. not enough to keep me from wanting to slap some writers for making a travesty of one of my favorite stories. :/
That having been said? I'd probably recommend it over the animated version; they /nailed/ Kaa. Even if Kipling did write him as male originally, it is, nevertheless, perfect, it /works/. Ms. Johanssen does a beautifully terrifying, hypnotic python-voice. For that alone...
But I grew up with the books, and the movies make a hash out of a lot of the rest of the characters, where they don't go and invent things (King Louie, for an example). That, I'm not so thrilled with.
And, yah. Disney. I wish they had thrown the original scripts out and picked up the book they were based off of; because Disney can and /has/ done darker fare, and done it well. I know they can; it's one of the reasons I was so disappointed.
