"In Indiana Jones, the hero’s improbable achievement was to survive a nuclear blast by hiding in a refrigerator. Hence, 'to nuke the fridge' means to introduce a wildly implausible element to a once-respected franchise, or more generally, to signal the abandonment of past standards of quality." [Times]

Unfortunately for me, I don't roll around in the comment threads of other sites, so I am just now learning that Indiana Jones and the Kingdom of the Crystal Skull haters have decided that "Nuke the Fridge" is the new "Jump the Shark." Because, you know, they couldn't handle the campy opening scene in which Indy escapes a nuclear blast by hiding in a lead-lined refrigerator. I guess it does lack the gritty realism of faces being melted by one Biblical relic and a gut-shot being instantly healed by another or, say, using an inflatable raft as a parachute, or a thousand year-old knight or... Anywho...
