I think out of the four films in the Indy saga, Temple has always meant the most to me. Does it have problems? Yes, but above all I pride it for its originality and mood. Temple wasn't a mere pastiche of Raiders, but rather a completely original film which paid homage to the serials of the 1930s before it, but in a darker vein. Indy himself is seen in a completely different lens as well, his rougher and cynical side that was only hinted at in Raiders coming out in full force. Throughout the movie, he's mainly out for himself and his own "fortune and glory", which makes his transition into caring hero so much more valuable. I get that there's some goofiness to the film, and some annoying moments, but it all pays off. The action sequences and cinematography in the film are incredible, and whenever I watch them I feel as if I'm actually there with Indy and his companions, something most films can't accomplish. And to top it off, Amrish Puri has a chillingly fantastic performance in the film as Mola Ram, varying from darkly mystical to borderline psychopathic in his bloodlust.
Finally, one of the reasons I have such a personal connection to the film was because it was filmed in my dad's home country of Sri Lanka, and when I watch the film I can even translate a bit of what the villagers are saying. To add to that, D. R. Nanayakkara (the actor who portrayed the shaman in Temple) was a family friend of my dad's. I appreciate that Spielberg and Lucas were willing to stray the path and create a masterful sequel that delved into non-Western themes, especially when dealing with the lingam, which I think was one of the best artifacts in the series. From start to finish, the film is pure fun, plain and simple.
