For the most part I still enjoy the show, mainly because of Stallone, but I get what you mean. The way the scenes are shot and delivered are strange; sometimes very short, almost comedic scenes which may have little or no bearing on the main flow of the story, and usually with Stallone making a pun or grinning at the end. It reminds me a bit of the way 90s sitcoms were often shot only without the drum roll or the little musical jingle as the scene ends. The showrunners may feel it's giving Tulsa King its own unique feel and style, but as you say, it comes at the expense of tension and leads to an inconsistency in the overall tone.
