Hey, @exyle.
A personal fun fact, one related to Temple of Doom. As far as I can remember, we didn't see a whole lot of movies when they first came out, and it was a while before we actual got a VCR player, so we didn't often see them whenever they went to those.
But somehow, I'd managed to see Raiders of the Lost Ark, and when I went to college for the first time, Temple of Doom was out. My dad drove me down to school and was helping me settle in, and we ended up that evening going to see Temple of Doom. It's the only movie I remember seeing with him, just the two of us, and while it's certainly not the best of the three (even though I actually acknowledge there are four :), I remember it rather fondly for that.
But you're absolutely right. Quite a bit darker, quite a bit more violent—just tonally different all around.
RE: Indiana Jones and the Temple of Doom is a different movie than I watched as a kid.
