you feel this way because you're emotionally invested in American shenanigans. i have no such attachments so i can look at this objectively... them British Isles boys are smacking up Boardwalk. And i like boardwalk...
Ehhh. Boardwalk is just a "bigger" more compelling show. More interesting characters, its better at incorporating historical events in to the story, it spans way more locations and it actually has well written black characters (if thats what you mean by "invested in American shenanigans", then you're right). Peaky Blinders is Boardwalk Light.
Tommy is cool, cuz he's the protaganist. After that the most interesting character is the Aunt's long lost son. The flashbacks to the ware are also interesting. But that about it...
And be serious. You really believe Lucky Luciano, Myer Lansky, Arnold Rothstein and Dr. Narcisse the Garvey-ite aren't better characters than Tommy Shelby and his dysfunctional family of gypsies??
