Reboot. Reboot! REBOOT!
I thought I'd try to raise this thread from the dead (I made a rhyme!) with a thought on a sequel that I didn't think was so good, The Jungle Book 2.
When I first saw it (back when I paid no attention to plot structure, whatsoever) I thought it was the best sequel I'd ever seen. However, going back and watching it again just recently, I was sorely disappointed. The plot was basically just the first in reverse.
After seeing the stuff about the original Jungle Book's story treatment on the Platinum Edition DVD I was thinking that it would've been a better idea to revive the second half of that (not knowing if it was in the book or not), which involved a hunter, Buldeo, using Mowgli to get at a treasure under the monkey's hideout, as the plot.
While I'm not sure that there is anyone who will agree with me, I thought it would have been a good idea.
