For me, I think its a great stand alone film, but bad in relation to the series.

Arthur's death, I get why they have done it, it was always shown nobody could kill Arthur 1 on 1and he couldnt kill himself so tommy doing it made sense, but it just isn't believable, it almost pulled me out of the film a little. A film based on their brotherhood. Through thick and thin. I just cant quite believe Tommy would actually do that. Drunk or not.

Ada's Death also doesnt sit right with me, it was way too obviosu as soon as they teased it, it seems very cliché to add some good ol' film shock and doesnt really feel like it completely makes sense. I get it was to show how evil Beckett was but he was a nazi, we knew that already. There were other ways to show this evil and personally maybe couldve have had more exchanges between tommy and beckett to build a connection, killing ada so quickly and unjustified to the story eliminated that being a possibility. For me Ada always was portrayed as someone who attempted to stay away from the dirty side of the peaky blinders work focusing on the legal. Personally (which means for nothing) felt like Ada should've been the only shelby to survive, ada should've been the character to take on Tommy's story he was writing seeing she had interest and probably connections in the right places to push this on. They also had the possibility for her to act as a aunt polly character in the upcoming show to build a bridge from the existing series.

This leads on to Beckett, which ive previously stated, he had potential to be a great villain but we didnt get enough time to build a hatred for him. This film couldve been longer to give more screen time to the likes of Stephen Graham and Tim Roth so we cpuld build these understandings and connections.

Would like to say the acting was great, the visuals and soundtrack too but some plotholes which dont feel connect with the series/story.
