Yes, no idea's original. The saviour from another culture trope is centuries old, and will continue for centuries still. But there was incessant hype over this movie that, besides the visuals, probably wasn't warranted, so there was bound to be some backlash. When there are stories of people wishing they could die and live in that world, you gotta have someone say pump your brakes. As mentioned, if the trope is executed well the movie will do well. I'm in the group that thinks this version of Ferngully was average at best, and nowhere near the level of praise it gets at worst.

But hey. If you (maybe the royal 'you') like it, I love it. Not about to try and change anybody's view on this movie. I do feel a little bad at people that invested in those 3DTVs though.
