This movie irritated me so much in many ways, but the main irritation would be the history facts. MISINFORMATION would be the correct word to describe this movie, as so many mentioned here I came to see this movie only for Tesla and he got a really small part in both appearances and credit, the story is half true. I recomend strongly to read a lot of articles about the TRUE stories about Nikola Tesla. It's really dissapointing that hollywood tried to do the exact same thing as Edison that the others tried to do back then to Tesla: ignore him, undermine, discredit him, irritate him.
Also, the movie making is really upsetting, at least that we are all on coke, we hardly have this really fast dialogues in real life and music is intrusing evertytime, didn't like it specially when you know a lot of facts of Tesla and the thief Edison. I found it really dangerous when movies claim going about real life stories and what they do is distort reality. Go do yourself research and then watch it so you can half some background when watching it.
