Honestly it was great movie not a awesome movie. It was something new and they took a big risk. (did it pay of yes or no that's debatable)
Yes the script can use a bit of twicking.
There's a few key factors lacking in the movie it self. But the acting was good and they had amazing acting talents to work with. But unfortunately your talented cast can only do as much. I truly believe if they had a better script and a better director this movie could've been a big box office hit. This is merely my opinion
