Wasn't it the Temple of Doom that resulted in creating the PG-13 rating as it wasn't really R but many found it too violent/intense for PG?
Also, when I watched Raiders, I found the soft focus/blurry scenes most prominent in the very end when Indy and Marion are walking down the steps after Indy met with folks about where the Ark is being stored. I noticed others but not as distracting.
Looking forward to watching TTOD and TLC.
