The first season of that show is all about building the world and the characters. I got really into the slow burn because it made the big moments hit harder later on. Sometimes a show needs time to lay the groundwork before the plot takes off. I'd say give the second season a shot before you write it off completely.
Man, six hours is a lot of time to give a show. That's a whole work day! I don't blame you for being done with it. Sometimes a slow burn just feels like a show that doesn't know where it's going. If you're not hooked by now, maybe just cut your losses. Life's too short for bad TV.
