Temple of Doom was an early example of an inappropriate descent into the dark and gritty fad; sort of a precursor of what was to come over the next quarter century.
I agree. The first time I watched the Indiana Jones trilogy together, "Temple of Doom" was the only one I didn't like. I'm not averse to gore generally. I laughed my ass off at the gore in "The Thing", but in this movie it just felt inappropriate and bothered me.
I'll never forget the scene of a heart being realistically ripped from a chest. Way out of place in what should be a light-hearted fun summer adventure movie. I wasn't keen on the poverty either, with beggars coming up to Indiana Jones and his friends. I know there was some rather macabre violence in the first one with the Nazis being melted, but that just looked cool. The gore in the sequel, on the other hand, was simply disgusting and contradicted the movie's otherwise lighter tone.
The kid sidekick and the wacky loudmouth female love interest had me believing this would just be a pleasant movie, and then there was all this grotesque stuff thrown in. Most people who don't like the movie seem to complain about Willie and Short Round, but I didn't mind them. Willie even amused me. It was just all the dark, depressing, and violent content that bothered me. That mine cart scene at the end is incredible, though. It almost redeems the rest of the movie. That scene is worth the price of admission alone, but the rest isn't so good.
