Literally everything about Shere Khan was contrived
-He kills Akela and the wolves literally do nothing, even though they could overtake him with sheer numbers; instead they just stand there like bitches, and fear just isn't a good enough excuse for it. For all their talk of wolf pack strength, they had nothing.
-Baloo attacks and almost beats Shere Khan but the rest of the kingdom doesn't help him to make sure the tiger's done for, because if they did they'd crush him. Instead they leave Baloo to fend for himself and Baloo loses (as if a tiger could kill a frikkin' 850lb bear).
-There's a bunch of frikkin' rhinos among them. All they had to do was gore Shere Khan once while he was distracted with Mowgli AND JUST ABOUT EVERYBODY ELSE. But again, the rhinos just stand there like idiots.
-Shere Khan fights and fails to kill Bagheera several times despite handily beating him each time. LOL!
-The rest of the animals finally get off their butts to prevent Shere Khan from catching Mowgli... and Shere Khan somehow manages to overtake everyone. DOUBLE LOL!
I'm sorry, but everything about how Shere Khan was written, save Idris Elba's presence and delivery, just sucked, plain and simple.
