This movie is scoring well with 98% on rotten tomatoes and 7.9 on imdb. I loved it and while it's almost entirely a fictional work (in particular, none of the characters are even remotely similar to the people that led RIM)... it really hits on the feeling of a fast scaling startup challenging incumbents with innovative hardware.
