Hopefully this is spoiler free enough for you all but saw it tonight in France and a few things about the french experience
1) only 2 people were in costume for a 5pm showing
2) the theater wasn't full, which was surprising since every showing after was sold out
3) MK2 theaters or at least the one near the presidential library are pretty effin nice
4) We felt reasonably comfortable discussing the movie after in a cafe since pretty much everyone else around was speaking a different language, total bonus
5) Instead of various candies they had a popcorn "bar" where you could put one of 12 different toppings on the popcorn. Salted Caramel was tasty.
As for the movie once JD opens it up I'll share my thoughts but for now my recommendation is to get in a foxhole because some people will not be able to shut their yaps.
