It's kinda funny. The serial killer Paddy was crushed and easily outwitted by the unsuspecting lady ultimate killer Lorraine who caused the death of Ciara.
The plot definitely trying to portray some brotherly romance between Ben & Paddy for several occasion.
James McAvoy can be easily mistaken as Russell Crowe. Just like how we find Ryan gosling and Ryan Reynolds interchangeably. Once Paddy & Ciara were dead, how are ben & Lorraine gonna get back 200k pounds back? They shd not have let Ant smash Paddy to death. In the final scene, How could they just drive off in gas-free tesla literally broke..
