Lmao, no it isn't. At best, it's made for people who are lightly into space/science and also lightly into cinema, so please don't trot out the "you need a high IQ to enjoy this movie" stuff. If it were made for space nerds, two scientists selected for deep space flight wouldn't need to stop and explain what E=MC² is to one another.
That's kind of always been Nolan's schtick, though, and I guess it's working out for him because he's got the a huge, quite passionate fan base. I'll never understand the hype and find his movies quite mid as cinema, but eh.
Really? I found it to be extremely mid. It took at least an hour for the film to not feel like a trailer montage and find proper pacing. The writing didn't feel organic at all, and felt like actors reading historical quotes from a page at each other. Also, when Florence Pugh's character started riding Oppenheimer's dick while he said his famous Bhagavad Gita line, I burst out laughing in the theater and had a really hard time taking the rest of the movie seriously.
I think this movie will be forgotten in 3 years, if not sooner.
