Nuking the fridge
I thought I'd bring this up once again and point out one thing that hasn't been mentioned before, like how the hell would the extremely heavy fridge (lead is heavy), inside a house on the bottom floor, be BLOWN CLEAR during the explosion. The exploding wooden house fragments in the blast didn't fly straight up, so why did the much heavier fridge do so? And I think the house would've collapsed onto the fridge, tons of wood and all, before it even did that, burying Indy in a fridge coffin so he'd never get out, not to mention being exposed to radiation and maybe the lead melting, and the heat and asphyxiation.
No, having the fridge fly clear (and ONLY this fridge) was Steven Spielberg's SINGLE BIGGEST DIRECTING BRAIN FART, and it's no wonder he's not directing Indy 5. And nuking the fridge is not the only stupid thing he did in Crystal Skull. Spielberg turned senile during the making of this movie. End of.
