Watched the "refrigerator scene" on YouTube and saw this comment in the stream that just about sums it up:
And you're okay with all of that, but once Indy goes into a lead-lined fridge and survives a nuclear blast, you guys call it "unrealistic." Just shut up and embrace the absurdity, like you did before. I personally thought this scene was awesome. The movie, I'll admit, not as good as the others, but definitely didn't deserve the flack.
