Good but could have been much better (and a plothole)
I thought the first 30 minutes were excellent, original, fast, with innovative camera work and a gripping story. It got less original and a tad mundane in the last 2/3 of the movie rehashing topics like the Russian mafia and the Wall Street backroom deals. The murder subplot was a also a little murky and needed more attention. Overall, still a good movie with an interesting premise.
Minor plothole: when the police arrives at the murder scene and Eddie is taken to the station for questioning, he would normally be searched. In a realistic scenario they would have searched him (and found the pills)
