It was good, but you don't need to watch it in an Imax like I did bc there isn't an amazing nuclear bomb explosion scene since Nolan doesn't use CG, and he didn't reuse any historical footage. Also, the move could really be condensed to 2 hours, it's just way too long at 3 hours.
Great subject matter and def should watch it, but feel a little led on bc everyone said to watch it in Imax and that was a waste of time and money. Like when it was over, I felt like thank god I can leave the theater now. Stream it to a TV, and don't waste your $ on tickets and popcorn at the theater. Def not his best work like some people say. At the end of the day, it's a glorified documentary from a really good filmmaker.
