I loved the fridge scene, it was fun and I never understood the complaints about it when there are other similar far fetched things in the entire series. A Knight that has lived for several hundred years, the spirit of God from the first movie and so many other implausible things that never bothered me.
I love movies that features aliens and the Indy franchise had dealt with so many other things that it felt natural to me. I loved the most recent movie and did not have a problem with it.
