First of all, the acting by Jake was very good and believable. His character is very interesting to watch. The storyline, characters, everything is good in this movie. But I give it a 3 stars in Common Sense meter. Some of his actions, are very questionable and makes you wonder, why he isn't in prison right now. Like, he has some plot armor or some thing.
Also, he appears to have just spawn into existence when the movie starts. Like, we don't get to know, why he is such a psychopath, where's his family, and if he's so clever and smart since childhood, then why was he unemployed in the first place? And why he doesn't have some kind of criminal record, if he was a thief before getting into news buiseness and if he did had a record, then why wasn't he under investigation the first time, he witnessed live murder.
But overall, it's a fun watch.
