These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Mola Ram kidnaps children from their families and forces them to work like slaves in dangerous mines for the stones and beats them mercilessly...and brainwashing them to the Cult of Kali. If Indy hadn't arrived on time, it could be possible that the cult would have killed the children anyway. And there's the way he sacrifices people to Kali Mah... all of which make him the most evil villain throughout the whole Indiana Jones franchise, which is quite the accomplishment in a franchise that features Nazis and Adolf Hitler himself.
The Scrappy: Willie. By God, is she annoying. Not helped by the fact that she screams constantly and is made up of nothing but female stereotypes. Even her actress called her "not much more than a dumb screaming blonde".
Special Effects Failure: The movie contains some fairly obvious matte paintings. But most notably, Mooks fall into crocodile-infested water and... cut to crocodiles eating empty clothes with scream sound effects dubbed over.
Not to mention Willie herself, as she is a culmination of the worst sexist stereotypes about women ever put together in a movie (vain diva, screaming damsel-in-distress, dumb blonde, useless hostage, etc).
